Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to a separated combined tunnel widening section trolley. Background Art

[0002] In the construction of the secondary lining of highway tunnel projects, the mainstream construction method is to use a secondary lining steel form trolley for formwork support and then pour concrete. For longer tunnels, there is generally a widened section with an emergency parking belt. When constructing the secondary lining of the emergency parking belt, a widened section secondary lining trolley is used.

[0003] The prior art (publication number: CN108979672A), an assembled trolley for tunnel widening section construction, discloses that the trolley main frame includes a first trolley main frame and a second trolley main frame. Between the first main cross beam of the first trolley main frame and the second main cross beam of the second trolley main frame, between the first upper cross beam of the first trolley main frame and the second upper cross beam of the second trolley main frame, and between the first top formwork of the first trolley main frame and the second top formwork of the second trolley main frame, they are respectively connected by bolts. On the outer sides of the first trolley main frame and the second trolley main frame, fixed formworks, side formworks and bottom formworks that are connected to each other are respectively arranged from top to bottom. The present invention can complete the efficient construction of the tunnel widening section by combining two trolley main frames, significantly saving manpower, material resources and working hours, ultimately saving the construction cost and avoiding the delay of the construction period; at the same time, the two trolley main frames are connected by a splicing method, and the transfer of the entire trolley can be easily realized.

[0004] Since the trolley frame for pouring the widened section is narrower than the conventional trolley main frame, and the side formwork connected to the side wall of the widened section trolley frame has a large mass, the stability of the widened section trolley frame is poor, which easily causes the widened section trolley frame to tilt during movement, posing a certain safety hazard. Therefore, we propose a separated combined tunnel widening section trolley to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a separated combined tunnel widening section trolley to solve the problem of poor stability of the widened section trolley frame.

[0006] To achieve the above object, the utility model adopts the following technical scheme: A separated and combined tunnel widening section trolley, including a main trolley frame and a secondary trolley frame. Both the main trolley frame and the secondary trolley frame are arranged on the ground, and the main trolley frame and the secondary trolley frame are detachably connected. A first side plate is arranged on the outer wall of the main trolley frame, and a second side plate is arranged on the outer wall of the secondary trolley frame. A number of columns are arranged at the upper ends of both the main trolley frame and the secondary trolley frame, and a top formwork assembly is jointly arranged at the upper ends of each column. The top formwork assembly includes a first fixing plate, a second fixing plate, a first top plate and a second top plate. One end of the first fixing plate is connected to the first side plate, and the other end is connected to the first top plate. One end of the second fixing plate is connected to the second side plate, and the other end is connected to the second top plate. The adjacent ends of the first top plate and the second top plate are detachably connected. The value range of the mass ratio of the second top plate to the second side plate is 0.7 - 0.9.

[0007] The beneficial effect of this scheme is: By dividing the top formwork assembly into a first fixing plate, a second fixing plate, a first top plate and a second top plate, when it is necessary to move the main trolley frame and the secondary trolley frame to the next widened section, by disconnecting the main trolley frame and the secondary trolley frame, and at the same time disconnecting the first top plate and the second top plate, at this time, the first side plate, the first fixing plate and the first top plate move along with the main trolley frame. Since the main trolley frame is wider and the first top plate is located at the upper end of the main trolley frame without destroying the balance when the main trolley frame moves, the main trolley frame can move smoothly. When moving the secondary trolley frame, the second side plate is located on one side of the secondary trolley frame, and a part of the second top plate is located at the upper end of the secondary trolley frame to increase the overall center of gravity of the secondary trolley frame, and the other part extends to the side of the secondary trolley frame away from the second side plate to maintain the balance of the secondary trolley frame. When the value range of the mass ratio of the second top plate to the second side plate is between 0.7 - 0.9, the secondary trolley frame will not tilt when moving, increasing the stability of the secondary trolley frame when moving.

[0008] Preferably, as an improvement, the second side plate includes a main side plate and a secondary side plate. The main side plate is arranged on the outer wall of the secondary trolley frame, and the secondary side plate is detachably connected to the main side plate. The value range of the mass ratio of the secondary side plate to the main side plate is 0.2 - 0.3.

[0009] The beneficial effect is: By splitting the second side plate into a main side plate and a secondary side plate, and making the value range of the mass ratio of the secondary side plate to the main side plate be 0.2 - 0.3, when it is necessary to move the secondary trolley frame, disconnect the secondary side plate from the main side plate, thereby further reducing the weight on one side of the second side plate of the secondary trolley frame, further improving the stability of the secondary trolley frame when moving, and at the same time reducing the overall weight of the secondary trolley frame, facilitating the movement of the secondary trolley frame.

[0010] Preferably, as an improvement, the column on the upper end of the main trolley frame near the secondary trolley frame is detachably connected to the lower end of the second top plate.

[0011] The beneficial effects are as follows: By connecting the second top plate to the column on the upper end of the main trolley frame near the auxiliary trolley frame, the stability of the connection between the main trolley frame and the auxiliary trolley frame can be further increased.

[0012] Preferably, as an improvement, the lower end of the first fixing plate is connected to the side of the main trolley frame away from the auxiliary trolley frame, and the second fixing plate is connected to the side of the auxiliary trolley frame away from the main trolley frame.

[0013] The beneficial effects are as follows: By connecting the first fixing plate and the second fixing plate to the main trolley frame and the auxiliary trolley frame respectively, the stability during the connection of the first side plate, the second side plate and the top die assembly can be further increased.

[0014] Preferably, as an improvement, pouring windows are provided at the tops of the first side plate, the main side plate, the first fixing plate, the second fixing plate, the first top plate and the second top plate, and a grouting port is provided at the top of the first top plate.

[0015] The beneficial effects are as follows: The first side plate, the main side plate, the first fixing plate, the second fixing plate, the first top plate and the second top plate are poured through the pouring windows, and the grouting port is used to fill the gaps at the top of the first top plate to prevent voids in the pouring.

[0016] Preferably, as an improvement, reinforcing ribs are provided inside the auxiliary trolley frame, and the reinforcing ribs are located directly below the second top plate.

[0017] The beneficial effects are as follows: The reinforcing ribs can not only improve the overall strength of the auxiliary trolley frame, but also increase the weight on one side of the second top plate, thereby further increasing the stability during the movement of the auxiliary trolley frame.

[0018] Preferably, as an improvement, the mass of the first top plate is set to 11 tons, the mass of the second top plate is set to 9 tons, the mass of the main side plate is set to 8 tons, and the mass of the auxiliary side plate is set to 2.5 tons.

[0019] The beneficial effects are as follows: When the mass of the second top plate is 9 tons and the mass of the main side plate is 8 tons, the mass of the auxiliary trolley frame is the lightest, and it does not affect the stability of the movement of the auxiliary trolley frame.
