Reinforcing beams may be connected between any two of the cross beams, the longitudinal beams, and the vertical beams 22 to reinforce the structural strength of the entire gantry 20. The structure of the door frame 20 adopted in the embodiment is not only simple in structure and easy to assemble, but also has sufficient strength, and provides guarantee for smooth laying of the waterproof board 110.

It should be noted that (the same applies hereinafter) the transverse direction, the longitudinal direction, and the vertical direction in the present embodiment respectively refer to a direction along the width direction of the tunnel as the transverse direction, an extending direction of the tunnel as the longitudinal direction, and a height direction of the tunnel as the vertical direction when the cart 10 of the waterproof sheet 110 is located in the tunnel. For example, the bottom beam 21 extends in the longitudinal direction, i.e. when the trolley is located in a tunnel, the bottom beam 21 extends in the direction of extension of the tunnel.

In this embodiment, as shown in fig. 1, 6 to 8, an arc-shaped rail 23 is mounted on the gantry 20, the arc-shaped rail 23 is used for the movement of the laying trolley 90, and the arc degree of the arc-shaped rail 23 is adapted to the tunnel arc degree required for laying the waterproof board 110. The laying carriage 90 may be mounted directly on the curved track 23 or indirectly on the curved track 23 via a connection. For example, two arc rails 23 may be provided, two arc rails 23 are respectively provided at both sides of the gantry 20 in the longitudinal direction, and the laying trolley 90 may be installed between the two arc rails 23 through a connection rod, and the connection rod drives the laying trolley 90 to move. Or each arc-shaped track 23 is respectively provided with a laying trolley 90 which can be set according to the actual situation.

In this embodiment, the movable template 60 is the arc structure and with the tunnel adaptation that needs laid, and the movable template 60 is the mode of arc structure has the multiple, can be that the movable template 60 sets to the overall structure of an inseparable and be the arc structure, also can be that the movable template 60 is formed by polylith sub-template swing joint, and a plurality of sub-templates can change mutual positional relation through the activity, and then make whole movable template 60 demonstrate the arc structure with the tunnel adaptation.

The movable template 60 is movably installed on the door frame 20 and is used for enclosing a filling space 70 with the primary support layer 120, and the filling space 70 is used for filling the bonding material 80. Specifically, in this embodiment, the movable mold plate 60 includes a top mold 61 and two sets of side molds 62, and the top mold 61 may be connected to the gantry 20 through an air cylinder, an oil cylinder, or a hydraulic cylinder, so that the top mold 61 may move up and down to be close to or away from the primary support layer 120. Or the top mold 61 may be fixed on the gantry 20, and the lifting of the top mold 61 may be realized by driving the gantry 20 to lift by the lifting mechanism 40, which may be determined according to the actual situation.

The two groups of side dies 62 are respectively hinged to two opposite sides of the top die 61 in the transverse direction, each group of side dies 62 is movably connected with the door frame 20 through a telescopic part, and the telescopic part can be an air cylinder, an oil cylinder or a hydraulic cylinder. Before the adhesive material 80 is filled, the side mold 62 can be contracted to reduce the space occupied by the waterproof board 110 trolley 10, so that the waterproof board 110 trolley 10 can move, center and the like conveniently, the situation that the waterproof board 110 trolley 10 is easy to collide with a tunnel in the moving or centering process is avoided, and the construction efficiency is improved.

In addition, there are various ways for the movable mold 60 and the primary support layer 120 to enclose the filling space 70, and the movable mold 60 may be directly manufactured into a semi-enclosed structure having an opening, and when the movable mold 60 moves to the primary support layer 120 and abuts against the primary support layer 120, the primary support layer 120 may seal the opening on the movable mold 60, thereby enclosing the filling space 70. The movable die plate 60 may be moved to face the primary support layer 120 with a certain gap therebetween, and then both side ports in the longitudinal direction and both side openings in the transverse direction may be blocked by the end dies 64, the small side dies 63, the blocking air bags 65, or the like. Or the movable template 60, the primary support layer 1 part where the waterproof board 110 is to be laid and the primary support layer 1 part where the waterproof board 110 is already laid cooperate with each other to enclose the filling space 70 together, thereby increasing the laying continuity between the sections of the waterproof board 110 (to explain that the trolley 10 of the waterproof board 110 is generally laid forward section by section along the extending direction of the tunnel when laying the waterproof board 110)

Before the movable template 60 and the primary support layer 120 enclose the filling space 70, the waterproof board 110 is laid on the movable template 60 by the laying cart 90, specifically, the waterproof board 110 is laid on the surface of the movable template 60 opposite to the primary support layer 120, and after the filling space 70 is filled with the adhesive material 80, the waterproof board 110 can be adhered to the primary support layer 120 by the adhesive material 80. Among them, the adhesive material 80 may be a material having fluidity such as lightweight concrete, adhesive mortar, or the like and having adhesiveness when cured.

The filling space 70 may be filled with the adhesive 80 in various ways, and the filling space 70 may be filled with a slip casting with a mold, or the filling space 70 may be filled with the adhesive 80 through a slip casting pipe by opening a slip casting port in the end mold 64 of the movable mold 60.

When the waterproof board 110 is laid by the trolley 10 for the waterproof board 110 of the invention, the waterproof board 110 can be quickly laid on the surface of the movable template 60 by the laying trolley 90, the movable template 60 drives the waterproof board 110 to move towards the primary support layer 120 and form the filling space 70 with the primary support layer 120, and finally, the bonding material 80 such as light concrete, bonding mortar and the like is filled into the filling space 70. It can be understood that, when filling lightweight concrete, because the waterproof board 110 is attached on the surface of the movable template 60, and the movable template 60 can provide enough support for the waterproof board 110, the surface that the bonding material 80 and the waterproof board 110 are bonded is flat and uniform, and then the waterproof board 110 can be flatly and uniformly laid on the uneven primary support layer 120, and the waterproof board 110 is prevented from being distorted, stretched or torn when being laid.

In one embodiment, as shown in fig. 6 and 7, in order to prevent the adhesive material 80 from leaking from both sides of the movable die plate 60 in the transverse direction when the adhesive material 80 is filled, the free end of each group of the side dies 62 is hinged with a small side die 63, and the small side die 63 is used for sealing the outlet of the filling space 70 at the small side wall 131 of the tunnel. Specifically, the tunnel has an inverted arch layer 130 vertically opposite to the support layer, a filling layer for the waterproof sheet 110 to run by the trolley 10 or the vehicle is laid on the inverted arch layer 130, and small side walls 131 adjacent to or connected with the support layer are formed on both sides of the inverted arch layer 130 in the transverse direction. After the movable formwork 60 is lifted and unfolded, the free end of each side formwork 62 is correspondingly positioned at the small side wall 131 and is spaced from the small side wall 131, and at the moment, the small side formwork 63 can be driven to be abutted and fixed with the support layer or the small side wall 131, so that the outlet of the filling space 70 at the small side wall 131 of the tunnel is sealed.

In other embodiments, as shown in fig. 6 and 7, the waterproof sheet 110 laid in the inverted arch layer 130 extends from the small side walls 131 on both sides, so that the waterproof sheet 110 laid on the supporting layer and the waterproof sheet 110 extending from the small side walls 131 can be welded, and then the small side forms 63 are driven, so that the two welded waterproof sheets 110 can be attached to the small side forms 63, thereby not only preventing the adhesive material 80 from leaking from the small side walls 131, but also increasing the flatness of the waterproof sheet 110 when laid.

In one embodiment, as shown in fig. 8, in order to facilitate the spreading of the waterproof sheet 110 on the movable die plate 60 and the enclosing of the movable die plate 60 and the support layer into the filling space 70, the movable die plate 60 further comprises an end die 64 and a plugging air bag 65, and the end die 64 and the plugging air bag 65 are detachably mounted between the movable die plate 60 and the support layer 120 for plugging the port of the filling space 70 in the extending direction of the tunnel. Specifically, after the top die 61 and the side die 62 of the movable die plate 60 move to positions opposite to the supporting layer and spaced by a certain gap, the end die 64 and the plugging air bag 65 can be directly installed between the movable die plate 60 (including the top die 61 and the side die 62), so that a filling space 70 is defined between the movable die plate 60 and the supporting layer, and the operation is simple and convenient, and the flexibility is strong.

While the filling space 70 generally has two ports in the direction of extension of the tunnel, two sets of end molds 64 and blocking bladders 65 may be provided to block the two ports, respectively. Only one group of end molds 64 can be arranged to block the air bags 65, one of the two ports is blocked by the end molds 64 and the blocking air bags 65, and the other port is blocked by the part of the primary support layer 1 where the waterproof board 110 is already laid, namely, the movable mold plate 60 can be overlapped with the part of the primary support layer 1 where the waterproof board 110 is already laid by a certain distance, so that the end surface of the part of the primary support layer 1 where the waterproof board 110 is already laid blocks the port of the filling space 70.

In one embodiment, as shown in fig. 1, in order to make the laying carriage 90 move more stably when pulling the waterproof board 110, two arc rails 23 are provided, and the two arc rails 23 are respectively provided at both sides of the gantry 20. Specifically, the two arc-shaped rails 23 can jointly support one laying trolley 90, so that the stability of the laying trolley 90 in pulling the waterproof board 110 to move is improved; the laying trolley 90 can be movably mounted on each arc-shaped rail 23 to more stably pull the waterproof board 110.

In other embodiments, the paving cart 90 is provided with an up-flow welder, so that the currently paved waterproof board 110 can be conveniently and quickly welded with the adjacent paved waterproof board 110 in a circumferential direction, or the lengths of the waterproof boards 110 paved on the movable formwork 60 in the circumferential direction can be welded in the circumferential direction.

In one embodiment, as shown in fig. 1, the bottom of the gantry 20 is further provided with a flashing bracket 100, the flashing bracket 100 is used for placing a flashing 110 to be laid, and the laying trolley 90 can pull the flashing 110 out of the flashing bracket 100. Specifically, in the present embodiment, the flashing bracket 100 is disposed near one side of the door frame 20 in the transverse direction, and the flashing bracket 100 includes two frame bodies disposed opposite and spaced apart from each other in the longitudinal direction, each frame body having a hook or a limiting groove. The initial state of the flashing 110 is a roll of flashing 110 wound on a rod by means of which the roll of flashing 110 is rotatably mounted on two frames. This facilitates the pulling of the flashing 110 from the roll of flashing 110 by the laying trolley 90.

In one embodiment, as shown in fig. 1, 4 and 5, the flashing 110 trolley 10 further comprises a plurality of running wheel assemblies 50 mounted at the bottom of the gantry 20 for moving the gantry 20, and each of the running wheel assemblies 50 is capable of independent steering. Specifically, the plurality of traveling wheel assemblies 50 are mounted at the bottom of the portal frame 20 and are used for driving the portal frame 20 to move, and it should be noted that the plurality of traveling wheel assemblies 50 may be mounted at the right bottom or the lateral bottom of the portal frame 20, for example, the plurality of traveling wheel assemblies 50 are mounted on the surface of the bottom (or the bottom beam 21) of the portal frame 20 facing the ground, that is, at the right bottom of the portal frame 20; as another example, the plurality of traveling wheel assemblies 50 are mounted on the bottom of the gantry 20 (or the bottom beam 21) on the side facing the tunnel primary support 120, i.e., on the bottom side of the gantry 20. The specific setting can be carried out according to the actual requirement.

In the embodiment, the projection of the gantry 20 on the ground is substantially rectangular, the number of the walking wheel assemblies 50 is four, the four walking wheel assemblies 50 are respectively installed at four corners of the gantry 20, and the four walking wheel assemblies 50 are oppositely arranged in pairs at intervals no matter in the transverse direction or the longitudinal direction, so as to support the gantry 20 and drive the gantry 20 to move more balance.

Wherein each of said running wheel assemblies 50 comprises running wheels 51, a steering linkage 52 and a steering drive member 53. Specifically, the steering link 52 may be a round rod structure, one end of which is rotatably connected to the gantry 20, and the other end of which is connected to a rotating shaft of the traveling wheel 51; the steering link 52 may be plate-shaped or cover-shaped, and in this case, the connecting shaft 521 may be rotatably connected to the frame 20, and the rotation of the running wheels 51 to the steering link 52 is not affected. When the running wheels 51 are rotatably mounted on the steering link 52, both ends of the rotating shaft thereof can be rotatably mounted on the steering link 52.

In other embodiments, a rotation bearing is installed between the rotation shaft of the running wheel 51 and the steering linkage 52, so that the running wheel 51 can rotate better to drive the gantry 20 to run. The steering driving component 53 can drive the steering connecting component 52 to rotate so as to drive the running wheels 51 to steer, and the steering driving component 53 can be directly connected with the connecting shaft 521 of the steering connecting component 52, so that the steering connecting component 52 is driven to rotate by directly driving the connecting shaft 521. It is also possible to drive the steering linkage 52 in rotation by means of a third party drive, for example in the form of a toothed engagement. The steering connecting piece 52 can be driven to rotate by the actual steering torque of the steering connecting piece 52, and the actual steering torque can be set according to actual needs.

At least some of the running wheel assemblies 50 are driving wheel assemblies, and each driving wheel assembly further includes a running driving member 54 for driving the running wheels 51 to rotate. For example, in this embodiment, the four wheel assemblies 50 are grouped in pairs, with the two sets of wheel assemblies 50 being longitudinally opposite one another, and the two wheel assemblies 50 in each set being laterally opposite one another. Two walking wheel assemblies 50 in one group of walking wheel assemblies 50 are driving wheels, so that the advancing and retreating of the waterproof board 110 trolley 10 can be better controlled, the required position can be rapidly and smoothly advanced or retreated, the operation is very convenient, and the construction efficiency is greatly improved.

Of course, when the conditions allow, the other set of running wheel assemblies 50 may be configured as a driving wheel instead of a driven wheel, that is, each running wheel assembly 50 is a driving wheel, so that the control of the running wheels 51 is more comprehensive, and the movement of the waterproof sheet 110 and the trolley 10 is better controlled.

The waterproof board 110 trolley 10 directly drives the whole portal frame 20 to move through the plurality of walking wheel assemblies 50 without laying steel rails in a tunnel, and each walking wheel assembly 50 can steer through the steering connecting piece 52 and the steering driving piece 53, so that the effect that the driving wheel and the driven wheel are independent from each other and can steer is realized, the waterproof board 110 trolley 10 is simple in structure and convenient to assemble, and can steer flexibly and automatically correct the deviation in the process of advancing forwards or backing backwards. In addition, the driving wheels and the driven wheels of the waterproof board 110 trolley 10 are all steered, so that the trolley is more favorably matched with the transverse moving mechanism 30 to realize the quick centering adjustment of the trolley, and the lining construction efficiency is improved.

In an embodiment, as shown in fig. 4 or fig. 5, the steering driving member 53 is a telescopic structure, and may be specifically a cylinder, a hydraulic cylinder, or the like. In this embodiment, the steering drive member 53 extends in a longitudinal direction and has one end rotatably connected to the mast 20 and the other end connected directly to the steering linkage 52 or indirectly through an intermediate linkage. Specifically, the steering driving member 53 has at least a spacing component in the transverse direction between the connecting position on the steering connecting member 52 and the connecting shaft 521, so that the steering driving member 53 applies a steering torque to the steering connecting member 52 when performing telescopic motion, and further drives the steering connecting member 52 to rotate and drive the running wheels 51 to steer. It will be appreciated that the steering drive member 53 is a telescopic structure and drives the steering linkage 52 with a steering torque, which not only allows the road wheel assembly 50 to be of simple construction and easy to assemble, but also facilitates steering of the road wheels 51.

In one embodiment, as shown in fig. 4 or 5, the steering linkage 52 includes a connecting shaft 521 and a mounting base 522 rotatably connected to the gantry 20 through the connecting shaft 521, the mounting base is connected to the steering driving member 53, and the traveling wheels 51 are rotatably mounted on the mounting base 522. In the present embodiment, the mounting seat 522 has a substantially cover structure with an opening facing downward, the traveling wheel 51 partially extends into the mounting seat 522, and two ends of the rotating shaft are rotatably mounted on two seat plates opposite to the mounting seat 522.

The arrangement of the convex plate 523 is beneficial to increasing the steering torque of the steering driving piece 53 to the steering connecting piece 52, so that the steering connecting piece 52 can be better driven to rotate when the steering driving piece 53 with smaller specification is used.

In one embodiment, as shown in fig. 4 or 5, since the convex plate 523 serves as a force bearing point for the steering driving element 53 to drive the steering connecting seat 221 and protrudes out of the mounting seat 522, in order to increase the structural strength at the position of the convex plate 523, a plate surface of the convex plate 523 away from the convex column is connected with a reinforcing rib.

In one embodiment, the mounting base 522 of the drive wheel assembly is further provided with a mounting boss on which the travel drive member 54 is mounted, so that the travel drive member 54 can rotate with the travel wheels 51 when the travel wheels 51 are steered, and further the structure of the travel wheel assembly 50 is more compact.

In one embodiment, the running wheels 51 are rubber wheels, which allows the flashing 110 to be better walked and steered on the trolley 10. In other embodiments, as shown in fig. 4 or 5, the running wheels 51 have a double-row structure, so that the pressure of the waterproof board 110 on each rubber wheel of the trolley 10 can be reduced, each rubber wheel in the double-row wheels is not overloaded, and the normal running and service life of the running wheels 51 are ensured.

The base 31 further has a top surface facing the gantry 20, the top surface is provided with a transverse guide rail 311 extending transversely, and the transverse guide rail 311 may be a slide rail structure, a guide groove structure or other guide structures, which are not limited specifically herein, and only need to be capable of cooperating with the sliding member 32 and allowing the sliding member 32 to slide.

One end of the sliding member 32 is slidably mounted on the transverse rail 311, and the other end is used for connecting with the platform truck 10 of the waterproof board 110. The specific shape and size of the sliding member 32 are not limited specifically, in this embodiment, the sliding member 32 is substantially a square column structure, and it can be understood that the overall strength of the sliding member 32 is better, so as to better drive the cart 10 of the waterproof board 110 to move transversely.

In one embodiment, as shown in fig. 1 to 3, the cart 10 of the flashing 110 further includes a lifting mechanism 40, one end of the lifting mechanism 40 is connected to the gantry 20, and the other end is connected to the sliding member 32 of the traversing mechanism 30. It can be understood that the lifting mechanism 40 can be used to drive the whole traverse mechanism 30 to lift, and when the traverse is needed, the lifting mechanism 40 can drive the traverse mechanism 30 to move downwards, so that the base 31 of the traverse mechanism 30 can contact the ground, thereby driving the waterproof board 110 to move transversely. When the transverse movement is not needed, the whole transverse movement mechanism 30 can be retracted through the lifting mechanism 40, so that the base 31 of the transverse movement mechanism 30 is separated from the contact with the ground, and the influence on the running of the trolley 10 of the waterproof board 110 is avoided.

Specifically, the outer shape of the sliding member 32 is fitted to the guide hole 211 so that the outer circumferential surface of the sliding member 32 can be in contact with the inner circumferential surface of the guide hole 211 and can slide relative to the guide hole 211.

In this embodiment, the lifting mechanism 40 is disposed above the bottom beam 21 and extends in a vertical direction, and one end of the lifting mechanism 40 is connected to the door frame 20, and the other end is hinged to the end of the sliding member 32 extending above the bottom beam 21 through a hinge shaft. Wherein, the articulated shaft can transversely extend, also can vertically extend, and specific can be set for by oneself according to actual need.

When the platform truck 10 of the waterproof board 110 of this embodiment needs to perform the lifting movement, the lifting mechanism 40 itself may be driven to perform the telescopic movement so as to make the gantry 20 and the sliding member 32 slide relatively, and further, the entire gantry 20 may be lifted after the base 31 of the traverse mechanism 30 is grounded. When the transverse movement is needed, the sliding part 32 can be driven to transversely move on the base 31, because the sliding part 32 passes through the guide hole 211 of the bottom beam 21 of the portal 20, the sliding part 32 can push the portal 20 to move by itself when the transverse movement is carried out, so that the portal 20 also carries out the transverse movement, and the lifting mechanism 40 arranged on the portal 20 can transversely move along with the portal 20 without pushing the portal 20 to move through the lifting mechanism 40, thereby avoiding the stress of the lifting mechanism 40 in the radial direction.

It can be understood that, because the sliding member 32 is hinged to the lifting mechanism 40, the connection between the lifting mechanism 40 and the sliding member 32 is more flexible and flexible, and has a certain movement margin, compared with the fixed connection between the sliding member 32 and the lifting mechanism 40, when the sliding member 32 starts to move transversely or the gantry 20 of the cart has a certain deflection, the connection between the lifting mechanism 40 and the sliding member 32 can be adjusted slightly, so as to greatly reduce the radial stress of the lifting mechanism 40, and avoid the influence of the large radial force on the lifting mechanism 40 on the service life of the lifting mechanism 40.
