Description

Two lining platform trucks turn over head of cloth by one window

The technical field is as follows:

the utility model belongs to tunnel lining equipment field, in particular to two lining platform trucks are by window cloth upset head, especially can realize man-machine cooperation, and the scheme of upset is controlled to the high efficiency.

Background art:

the construction of the secondary lining concrete of the tunnel takes a lining trolley as a template system, and then the concrete is pumped into a mold for pouring. The secondary lining trolley mainly comprises a portal frame, a bottom beam, a template hydraulic rod, an upper top frame, a top template and a side template; the material distributing system comprises a material distributing machine, a pouring pipe, a pouring window and the like. When the traditional method is adopted for carrying out two-lining concrete construction, in order to realize transverse, left, right, equal-height symmetry and longitudinal layered uniform pouring, a plurality of mold feeding windows (concrete feeding windows) are generally arranged on the left side, the right side, the upper part, the middle part and the lower part of a trolley in a layered mode along the axis direction of a tunnel, and concrete is conveyed to each mold feeding window from a conveying pump discharge port through a detachable conveying pipe. Of course, the act of arranging and removing the tubes one by one for each window lacks efficiency, and various assumptions are made for the operator, such as:

patent application No. 201220331471.7 discloses a distributing device based on two lining concrete construction trolleys in tunnel, including being used for carrying the switching-over pipe of concrete and being connected to the leading-in chute of a plurality of concrete of each income mould window department on the trolley, a plurality of leading-in chute tops of concrete are located to the switching-over pipe, and the exit end of switching-over pipe can change between a plurality of leading-in chutes of concrete. The efficiency problem is solved by installing the leading-in chutes at one time and distributing and pouring one by one, but chutes with different lengths and specifications are prepared, and the trouble in installation is increased.

And patent application number 201721893372.7 discloses a tunnel lining platform truck layering is by window pouring and cleaning system, including template unit, slip casting mouth, sprue gate, pipe-line system and cloth system, a plurality of template units connect gradually and form the domes and form the pouring area in the inboard of domes, wherein: the plurality of grouting ports are arranged at the vault position outside the arch structure and are arranged in the circumferential direction and the axial direction; the pipeline system comprises a plurality of concrete pipelines, one ends of the concrete pipelines are respectively led to each pouring gate, the other ends of the concrete pipelines are connected to the pouring gates, the material distribution system comprises a concrete pump, a feeding pipe, a material distribution trolley and a material distribution rack, the concrete pump is connected with the material distribution trolley through the feeding pipe, a track is arranged on the material distribution rack, the material distribution trolley moves on the track, a feeding port is formed in the material distribution trolley, and the feeding port corresponds to the pouring gates. The concrete is axially distributed one by one through the distribution trolley, but the troubles of pipe distribution and butt joint of the distribution trolley and each pipeline still exist.

Patent application No. 202010302225.8 discloses a novel hydraulic trolley for casting a tunnel secondary lining. The technical idea that the material distribution system is supported by the mechanical arm and the adjustment of up-down, left-right and extension is realized by matching with a pipeline rotary joint is provided, but systematic matching details are lacked.

How to overcome the traditional technique not enough, provide a window cloth equipment that can carry out one by one, become the utility model discloses the object of research.

The invention content is as follows:

the utility model aims at designing a two lining platform trucks who is fit for man-machine cooperation to control by three section return bend bearing connection turn-over head of cloth of chasing one's window.

The utility model discloses technical scheme realizes like this: the utility model provides a two lining platform trucks turn-over head of window cloth by one, includes return bend bearing and oil motor, its characterized in that: the three sections of bent pipe bearings are sequentially connected end to end in an embedded mode, the first section of bent pipe bearing is movably connected with the concrete pipe, and the pipe opening of the tail section of bent pipe bearing is a material distribution opening; the oil motor and the speed reducer in transmission connection with the oil motor are locked on the first section of bent pipe bearing, a driving chain wheel on an output shaft of the speed reducer is connected with a fixed chain wheel locked on the concrete pipe through a chain, and the oil motor drives the three sections of bent pipe bearings to rotate.

The fixed chain wheel is fixedly sleeved on the concrete pipe and is concentric with the concrete pipe.

The central angle of the elbow bearing is 90 degrees.

And an operating handle is welded on the surface of the tail section elbow bearing.

The utility model has the characteristics of reasonable design, simple structure, man-machine cooperation, easy operation and flexible control; particularly, the first bent pipe bearing and the concrete pipe are mechanically operated to reduce the manual load, and the tail bent pipe bearing is manually operated, so that the flexibility and the high efficiency are better, and the requirement of pouring window by window in a certain range is met.

Description of the drawings:

the present invention will be further explained with reference to the following specific drawings:

FIG. 1 is a front view of a cloth turning head

FIG. 2 is a schematic view of a rear view of a cloth inverting head

FIG. 3 is a schematic view of a bent-tube bearing

Wherein

1-first section elbow bearing 2-middle section elbow bearing 3-tail section elbow bearing

31-cloth opening 32-operating handle 4-concrete pipe

5-oil motor 6-speed reducer 7-driving sprocket

8-fixed chain wheel X-central angle

The specific implementation mode is as follows:

referring to fig. 1, 2 and 3, the two-lining trolley window-by-window material distribution turnover head comprises a bent pipe bearing and an oil motor, wherein the bent pipe bearing comprises three sections, namely a first section bent pipe bearing 1, a middle section bent pipe bearing 2 and a tail section bent pipe bearing 3, the three sections of bent pipe bearings are sequentially connected in an end-to-end embedded manner, and the joints of the two shafts can freely rotate by 360 degrees; the first section of elbow bearing 1 is movably connected with the concrete pipe 4, the pipe opening of the tail section of elbow bearing 3 is a material distribution opening 31, and therefore an operating handle 32 is welded on the surface of the tail section of elbow bearing 3, and the operation is convenient to hold by hands.

The oil motor 5 and the speed reducer 6 in transmission connection with the oil motor are locked on the first section of bent pipe bearing 1, a driving chain wheel 7 on an output shaft of the speed reducer 6 is connected with a fixed chain wheel 8 locked on the concrete pipe 4 through a chain, and the oil motor 5 drives the three sections of bent pipe bearings to rotate.

Further, the fixed chain wheel 8 is fixedly sleeved on the concrete pipe 4 and is concentric with the concrete pipe 4, so that the whole three-section bent pipe bearing can rotate by 360 degrees. If for simple process, also can fix fixed sprocket 8 in concrete pipe 4 one side, only the rotation angle can receive the influence of concrete pipe 4 point location, but also can satisfy the demand at the rotatory regulation of more than 180 degrees within range.

Referring to fig. 3, the central angle X of the elbow bearing is 90 degrees, i.e. three-axis rotation without dead angle can be formed. The use of elbow bearings with angles other than 90 degrees is certainly not excluded.

The related elbow bearing is a common part sold in the market in public.
