Abstract
The invention discloses a bolted shield launching bracket which comprises a bottom support (1), wherein the bottom support (1) is formed by connecting two symmetrically arranged base plates (2) via high-strength bolts, triangular reinforced rib plates (3) are also connected on both sides of the bottom support (1) via high-strength bolts, heavy rail supports (4) are also symmetrically and fixedly arranged on the bottom support (1) via high-strength bolts, heavy rails (5) are connected on the heavy rail supports (4) via high-strength bolts, the heavy rail supports (4) are obliquely arranged, the connecting lines of the central axes of the paired two heavy rail supports (4) form an included angle alpha, and the value range of the included angle alpha is 40-55 DEG. The bolted shield launching bracket has simple structure, ingenious design and reasonable arrangement, can be repeatedly disassembled and assembled and can ensure connection strength and accuracy.
Description
Technical field
The present invention relates to a kind of shield structure carriage, particularly a kind of bolt formula shield launching carriage.
Background technology
Shield machine is a kind of main equipment in the subway work; Shield launching is emphasis and the difficult point in the shield-tunneling construction process; Since the shield machine main body on the guide rail that starts, can not transfer to, therefore carriage and reaction frame are equipped with very high required precision, adopt the mode of welding between traditional each parts of shield launching carriage; Stress deformation might take place in the parts section bar in welding process on the one hand, thereby has influence on the installation accuracy of carriage and reaction frame; Simultaneously owing to adopt non-removable welding manner between each parts; After shield machine work is accomplished, also need adopt the mode of destruction that the various piece of carriage is taken apart, in case adopt this mode to dismantle; Just can't reinstall; Even reinstall by force, its precision also can receive great influence, does not possess practicality.Therefore need a kind of novel shield structure carrier structure that can address the above problem now.
Summary of the invention
The present invention is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, designs ingeniously, rationally distributed, can repeated disassembled and assembled be suitable for, and can guarantee the bolt formula shield launching carriage of bonding strength and precision.
Technical solution of the present invention is: a kind of bolt formula shield launching carriage; Comprise bottom support 1; It is characterized in that: described bottom support 1 is formed by connecting through high-strength bolt two symmetrically arranged base plates 2, is connected with triangle through high-strength bolt equally in the both sides of bottom support 1 and strengthens gusset 3, on bottom support 1, also is set with heavy rail support 4 symmetrically through high-strength bolt; On heavy rail support 4, be connected with heavy rail 5 through high-strength bolt; Heavy rail support 4 is obliquely installed, and the line of two paired heavy rail support 4 axis formation angle, and the span of this angle is: the 40-55 degree.
The present invention compares with prior art, has following advantage:
The bolt formula shield launching carriage of this kind of form of structure, it is simple in structure, designs ingeniously, and it adopts the mode of welding to connect to traditional shield launching carriage, exists to be difficult to dismounting, and the assembling of dismounting back is wasted time and energy, and can't guarantee problem such as installation accuracy; Its will start each parts of carriage utilizes high-strength bolt to connect as one structure, advantage such as the carriage that starts of present embodiment is had can dismantle as required at any time, re-assembly, and can also guarantee integrated carrying ability and precision simultaneously.The manufacture craft of this shield launching carriage is simple, and is cheap for manufacturing cost, therefore we can say that it has possessed multiple advantage, is particularly suitable for applying in the art, and its market prospects are very wide.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the vertical view of the embodiment of the invention.
The specific embodiment
Below with the accompanying drawings specific embodiment of the present invention.As shown in Figure 1: a kind of bolt formula shield launching carriage; Comprise bottom support 1 as the basis; Described bottom support 1 is spliced by two symmetrically arranged base plates 2 each other, and connects through high-strength bolt between the two, is provided with triangle symmetrically through high-strength bolt equally in the both sides of bottom support 1 and strengthens gusset 3; On bottom support 1, also be set with heavy rail support 4 symmetrically through high-strength bolt; The bottom of heavy rail 5 is welded with junction plate, and junction plate is connected with heavy rail support 4 through high-strength bolt, and symmetrically arranged heavy rail support 4 is obliquely installed; And each line to the axis of heavy rail support 4 forms an angle, and the span of this angle is: the 40-55 degree.
The bolt formula shield launching carriage of the embodiment of the invention becomes axially symmetric structure on the whole, and shield machine is seated on the heavy rail 5; Along bottom support 1 axially do rectilinear motion, the carriage that starts of this product just plays the effect of support to shield machine, get into the tunnel of oneself drilling out when shield machine after; Because starting of present embodiment all utilizes high-strength bolt to connect between each parts of carriage; Can disassemble comparatively easily, and be transported to the exit position in tunnel respectively, and assemble again.
The carriage that starts of present embodiment can use repeatedly, has saved a large amount of costs, and dismounting, easy for installation, quick, and can guarantee supporting capacity and precision.
Claims (1)
1. bolt formula shield launching carriage; Comprise bottom support (1); It is characterized in that: described bottom support (1) is formed by connecting through high-strength bolt two symmetrically arranged base plates (2); Be connected with triangle through high-strength bolt equally in the both sides of bottom support (1) and strengthen gusset (3); On bottom support (1), also be set with heavy rail support (4) symmetrically through high-strength bolt, go up at heavy rail support (4) and be connected with heavy rail (5) through high-strength bolt, heavy rail support (4) is obliquely installed; And the line of paired two heavy rail supports (4) axis forms angle, and the span of this angle is: the 40-55 degree.
