Description
Technical field
The utility model relates to underground construction field, especially a kind of versatility shield trolley sleeper.
Background technology
At present, known shield trolley sleeper mainly contains following several according to mode: one is integrating tunnel section of jurisdiction, and chassis sleeper is arranged on segment joint position, realizes the fixing, substantially with bolts of chassis sleeper; Another kind of and in tunnel, electric car sleeper is basic is connected, become to fix overall structure with tram rail pincushion, with bolts or be directly welded to connect, as application number 201120076802.2 shown type; Also have one to be exactly by installing mass-type foundation, mass-type foundation is fixing according in tunnel duct piece, and chassis electric car sleeper is fixed, as application number 201420354866.8 shown type according to realization in mass-type foundation.But when tunnel duct piece is fissure of displacement supporting, segment joint position is not fixed, chassis sleeper is difficult to be fixed on seaming position place very well.When adopting tunnel electric car and chassis mass-type foundation, all want because electric car sleeper is whole tunnel, so mass-type foundation needs whole tunnel to be paved with, and chassis sleeper only needs laying in chassis activity space just passable, and position is moved along with the movement of chassis.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art, provide a kind of versatility shield trolley sleeper, self gravitation by means of chassis sleeper make its can leaning support on other equipment being arranged on shield duct piece inside, thus complete the installation exercise of chassis sleeper easily.
The utility model object realizes being completed by following technical scheme:
A kind of versatility shield trolley sleeper, is arranged on shield duct piece inner wall surface, it is characterized in that: the bottom surface of described chassis sleeper is cambered surface, and a side of described chassis sleeper is welded with connecting rod.
The bottom surface of the described chassis sleeper in cambered surface is satisfied with makes described chassis sleeper be close to described shield duct piece inner wall surface.
Ribs is welded with between described chassis sleeper and the described connecting rod of its side.
Described connecting rod is U-type groove steel, and the notch of described U-type groove steel is downward.
The utility model has the advantages that: highly versatile, peace are torn open conveniently, structure is simple, be suitable for popularization.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross section of the present utility model constructional drawing;
Fig. 3 is top view of the present utility model;
Fig. 4 is use structural representation of the present utility model;
Fig. 5 is the partial enlarged drawing A of Fig. 4.
Detailed description of the invention
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
As Figure 1-5, mark 1-10 in figure to be expressed as: electric car sleeper 1, connecting rod 2, chassis sleeper 3, connecting rod 4, anti-springboard 5, fixed block 6, ribs 7, bolt hole 8, trolley track 9, shield duct piece 10.
Embodiment: as shown in Figure 1, versatility shield trolley sleeper in the present embodiment comprises symmetrically arranged two chassis sleepers 3, above two chassis sleepers 3, erection has trolley track 9 respectively, can move on the trolley track 9 that chassis 9 is erected at both sides on trolley track 9.Each trolley track 3 all offers two bolts hole 8, and trolley track 9 can be arranged between two bolts hole 8, and bolt hole 8 is for auxiliary fixed station Car Track 9.Connecting rod 4 is welded with in a side of chassis sleeper 3.Because chassis is erected on two trolley tracks 9 on two chassis sleepers 3, therefore in Fig. 1 of the present embodiment, connecting rod 4 is weldingly fixed on respectively on two relative sides of two chassis sleepers 3.Be welded with ribs 7 between connecting rod 4 and chassis sleeper 3, ribs 7 is indeformable for ensureing connecting rod 4.As shown in Figure 2, the bottom surface of chassis sleeper 3 is cambered surface, and the inner wall surface of this cambered surface and shield duct piece 10 is formed to be close to, with the inner wall surface making chassis sleeper 3 be supported on shield duct piece 10 all the time.
As shown in Fig. 2,3 and 4, the chassis sleeper 3 in the present embodiment incompatiblely completes installation by matching with electric car sleeper 1.Two electric car sleepers 1 are provided with the tramway for electric car movement.Two electric car sleepers 1 are integrally formed by the connecting rod 2 be fixedly installed between both opposite flanks.The cambered surface of coincideing with the inner wall surface shape of shield duct piece 10 is all arranged in the bottom surface of two electric car sleepers 1, with the inner wall surface making the bottom surface of electric car sleeper 1 be close to shield duct piece 10 all the time.Fixed block 6 is respectively arranged with at the outer surface of two electric car sleepers 1.The shape of the shape of fixed block 6, size and connecting rod 4, size are coincide adaptive.Two chassis sleepers 3 are respectively by being fixedly connected leaning support on the electric car sleeper 1 of correspondence position between connecting rod 4 and fixed block 6.Now, because chassis sleeper 3 is all positioned at the outside of electric car sleeper 1, and the position that electric car sleeper 1 compared by chassis sleeper 3 is higher, therefore, chassis sleeper 3 swings to electric car sleeper 1 by himself Action of Gravity Field, and connecting rod 4 just supports electric car sleeper 1 and realizes the stable of chassis sleeper 3.Stressed larger when chassis sleeper 3, the connecting rod 4 of chassis sleeper 3 is stressed larger, and chassis sleeper 3 is more stable.
The present embodiment is in the specific implementation: as shown in Figure 5, the connecting rod 4 in the present embodiment adopts H-type groove steel, and the notch of H-type groove steel is downward.The outer profile size of fixed block 6 and the notch size of H-type groove steel are coincide adaptive, and H-type groove steel is overlapped on fixed block 6.Above fixed block 6, be provided with anti-springboard 5, anti-springboard 5 is fixedly mounted on the side with the electric car sleeper 1 of fixed block 6 homonymy, and the effect of anti-springboard 5 is to prevent connecting rod 4 from upwards jumping out.
Although above embodiment elaborates the design of the utility model object and embodiment with reference to accompanying drawing, but those of ordinary skill in the art can recognize, under the precondition not departing from claim limited range, still various improvement and conversion can be made to the utility model, as: the fixed form of trolley track 9, the shape, size etc. of fixed block 6, therefore do not repeat one by one at this.
