Abstract
The utility model relates to the field of duct piece mould devices in a shield construction technology, in particular to a locking structure for a cover board of a duct piece mould. The locking structure comprises a cover board, wherein one side of the cover board is rotatably connected with a side plate on one side of the duct piece mould, a locking buckle is arranged on the other side of the cover board, a compression handle is hinged on the other side of the duct piece mould, which corresponds to a position of the locking buckle, the compression handle is rotatably provided with a connecting rod, and the connecting rod and the locking buckle are locked and fixed through the compression handle. By adopting the locking structure for the cover board of the duct piece mould provided by the utility model, when the cover board is locked, the cover board and the mould are located in a closed position, the connecting rod and the locking buckle are clamped, the compression handle is downwards pressed and rotated, and the compression handle is rotated around an articulated shaft, so that the cover board and the duct piece mould are locked through buckling the connecting rod and the locking buckle. The other auxiliary tool is unnecessary in a locking process, an operating process is simple, quick, low in operating difficulty and labor-saving, and the production efficiency for continuous prefabrication of duct pieces is greatly improved.
Description
Technical field
The utility model relates to the segment die device field of shield-tunneling construction technology, particularly a kind of locking mechanism of segment die cover plate.
Background technology
Along with the develop rapidly of urban construction, the scale of subway construction constantly enlarges, and the shield-tunneling construction technology obtains application more and more widely in subway construction.Shield duct piece is as the main concrete prefabricated element of subway shield tunnel construction, and its production technology is complicated, requires also more and more stricter.Wherein, the cast of each sheet shield duct piece need be accomplished by means of segment die.
Segment die comprises bed die, side form, end mould and cover plate.The cover plate of continuous segment prefabricated middle segment die needs constantly to open; The locking mechanism of prior art cover plate is than more complicated, in continuous segment prefabricated construction, and time-consuming, the effort of the locking operation of cover plate; Manipulation strength is big, has influenced segment prefabricated production efficiency.
The utility model content
The utility model provides a kind of locking mechanism of segment die cover plate to the problem that prior art exists, and is intended to improve the operating efficiency of segment die in prefabricated, reduces manipulation strength, reduces operation easier.
This is to realize like this with novel purpose newly; A kind of locking mechanism of segment die cover plate comprises cover plate, and the side plate of a side of said cover plate one side and segment die is rotationally connected; The opposite side of cover plate is provided with tight locking button; The opposite side of the segment die corresponding with the tight locking button position is hinged with and compresses handle, said compress on the handle to rotate be provided with connecting rod, said connecting rod and tight locking button fasten through compressing grip handle lock.
Adopt the locking mechanism of the segment die cover plate of the utility model; During the locking cover plate; Cover plate and mould are in the close position,, compress handle to pressing down to change with connecting rod and tight locking button clamping; Compress a winding by hand jointed shaft rotation, make the locking of connecting rod and tight locking button promptly realize the locking of cover plate and segment die.This locking process need be by other aid, and operating process is simple, quick, operation easier is low, and laborsaving, improves segment prefabricated production efficiency continuously greatly.
Be connected with the locking of tight locking button for ease of connecting rod, said connecting rod with compress handle and be articulated and connected.
For guaranteeing the locking intensity of cover plate, be provided with the adjusting nut that is used to regulate the connecting rod stroke with the said connecting portion that compresses the hinged connecting rod of handle.
For guaranteeing to compress the bonding strength of handle and mould, said segment die opposite side is fixed with fixed head, is fixedly connected with hinged seat on the said fixed head, saidly compresses handle and hinged seat is articulated and connected.
Description of drawings
Fig. 1 is the connecting rod and the tight locking button locking state figure of the locking mechanism of segment die cover plate.
Fig. 2 is the connecting rod and the tight locking button separated position figure of the locking mechanism of segment die cover plate.
Wherein, 1 cover plate; 2 tight locking buttons; 3 connecting rods; 4 compress handle; 5 hinged seats; 6 adjusting nuts; 7 fixed heads; 8 segment dies.
The specific embodiment
As Fig. 1, shown in Figure 2 be the locking mechanism of the segment die cover plate of the utility model; Comprise cover plate 1; The side plate of one side of cover plate 1 one sides and segment die 8 is rotationally connected, and the opposite side of cover plate 1 is provided with tight locking button 2, and the opposite side of the segment die 8 corresponding with tight locking button 2 positions is hinged with and compresses handle 4; Compress on the handle 4 to rotate and be provided with connecting rod 3, connecting rod 3 is locked through compressing handle 4 with tight locking button 2; Connecting rod 3 with compress handle 4 and be articulated and connected; The connecting portion of hinged connecting rod 3 is provided with the adjusting nut 6 that is used to regulate connecting rod 3 strokes with compressing handle 4; Segment die 8 opposite sides are fixed with fixed head 7, and wherein fixed head 7 is fixing with the welding of segment die 8 side plates, is connected with hinged seat 5 through bolt on the fixed head 7, compress handle 4 and are articulated and connected with hinged seat 5.
When locking cover plate 1; Cover plate 1 and segment die 8 are in the close position,, compress handle 4 to pressing down to change with connecting rod 3 and tight locking button 2 clampings; Compress handle 4 and rotate, make connecting rod 3 and tight locking button 2 lockings promptly realize the locking of cover plate 1 and segment die 8 around jointed shaft.When needs are adjusted the coupling mechanism force of connecting rod 3 and tight locking button 2, can pass through rotation adjusting nut 6, the stroke radius that changes connecting rod 3 is realized.Connecting rod 3 these locking processes need be by other aid, and operating process is simple, quick, operation easier is low, and laborsaving, improves segment prefabricated production efficiency continuously greatly.
The utility model is not limited to the foregoing description; Every on the basis of the disclosed technical scheme of the utility model; Those skilled in the art is according to disclosed technology contents; Do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the scope of the utility model protection.
