Abstract
A kind of shield machine universal connector, including vehicle body hanger, connecting plate is equipped between two vehicle body hangers, with connection axis connection between connecting plate and vehicle body hanger, oscillating bearing is equipped between connecting shaft and connecting plate, the oscillating bearing is universal ball bearing, spacer is additionally provided between universal ball bearing and connecting plate, have on the inside of spacer with universal ball bearing outside and match in the slot that spherical, described spacer is fixed on connecting plate, spacer upper end is fixed on connecting plate by gland.The utility model has the beneficial effects that realizing the variation of the support and connection, rotation and pitching movement between shield machine crossbeam and both ends waggon; the intensity for solving shield machine two sides car body connecting portion point is insufficient, climbing when angle too small, rotation when the excessive and bring part sliding surface serious wear that works long hours of turning lead to the significant trouble of the necessary shutdown maintenance of equipment; it ensure that shield machine can continuous uninterrupted stable carry out excavation operation; meanwhile demolition and maintenance are convenient.
Description
Technical field
The utility model provides a kind of shield machine universal connector, belongs to shield-tunneling construction field.
Background technique
Shield machine generally includes the shield body part of front and other auxiliary facilities at rear portion, usually to pass through between them
Connecting plate connection.Generally in such a way that articulated shaft is hinged, articulated manner can only guarantee most connecting plate currently on the market
Rear and front end or so is turned, and pitching generally can not be rotated up and down, only only pitching can only by connection plate hole and articulated shaft it
Between gap realize that the angle changing rate of flexion-extension is small, and it is tight commonly using will cause abrasion between connection plate hole and connecting shaft
Weight.Meanwhile it being utilized between connection plate hole and connecting shaft plus isolation wear-resistant sleeve to reduce abrasion someone, but wear-resistant sleeve or solid
Determine or be interference fitted in connecting plate, this form disassembly is inconvenient or is directly loadable between the two, and this form often results in
Isolation wear-resistant sleeve skids off, and can not play wear-resisting effect.
Summary of the invention
The utility model solves above-mentioned technical problem and provides a kind of shield machine universal connector, realizes shield machine cross
The variation of support and connection, rotation and pitching movement between beam and both ends waggon solves the connection of two side body of shield machine
Partial intensity is insufficient, climbing when angle too small, rotation when turning is excessive and the bring part sliding that works long hours
Surface wear seriously cause equipment must shutdown maintenance significant trouble, ensure that shield machine can continuously uninterruptedly stable progress
Excavation operation, meanwhile, demolition and maintenance are convenient.
The utility model solves the technical solution that technical problem uses:
A kind of shield machine universal connector, including vehicle body hanger are equipped with connecting plate, connecting plate between two vehicle body hangers
With connection axis connection between vehicle body hanger, oscillating bearing is equipped between connecting shaft and connecting plate, the oscillating bearing is ten thousand
To ball bearing, it is additionally provided with spacer between universal ball bearing and connecting plate, has on the inside of spacer with universal ball bearing outside and matches
It is spherical, the spacer is fixed in the slot on connecting plate, and spacer upper end is fixed on connecting plate by gland.
It is located on the outside of connecting shaft between above-mentioned universal ball bearing top and bottom and vehicle body hanger and is equipped with limited block.
Above-mentioned gland is bolted on connecting plate.
The utility model has the beneficial effects that
1, present apparatus reliably working, stable prolonged operation, reduction equipment should not be safeguarded in underground excavation operation
Drawback alleviates the workload of operator, reduces the working strength of operator；
2, the variation of the support and connection, rotation and pitching movement between shield machine crossbeam and both ends waggon is realized,
The intensity for solving shield machine two sides car body connecting portion point is insufficient, climbing when angle too small, rotation when turning it is excessive and
The bring that works long hours part sliding surface serious wear leads to the significant trouble of the necessary shutdown maintenance of equipment, ensure that shield machine
Can continuous uninterrupted stable carry out excavation operation, meanwhile, demolition and maintenance are convenient.
3, when shield machine is tunneled in construction in line with the drawings to when needing to turn round, this universal connecting plate can both keep original company
When connecing constant, driving turning needs can also be met；River, culvert are encountered when shield machine driving or are handed over other subway tunnels
It when can locate, needs to be tunneled downwards at a certain angle, be kept at an angle again after crossing the above barrier upwards
It is tunneled, height is tunneled with the work before returning to, continues Shield digging operation.
4, gland is connect by bolt with connecting plate, easy to disassemble.
Detailed description of the invention
It is illustrated below in conjunction with attached drawing with embodiment
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Referring to attached drawing 1, a kind of shield machine universal connector, including vehicle body hanger 1, the company of being equipped between two vehicle body hangers
Fishplate bar 2 is connected between connecting plate and vehicle body hanger with connecting shaft 3, and oscillating bearing 4 is equipped between connecting shaft and connecting plate, described
Oscillating bearing be universal ball bearing, be additionally provided with spacer 5 between universal ball bearing and connecting plate, on the inside of spacer with universal ball bearing
Outside, which has, to be matched in the slot 9 that spherical, described spacer is fixed on connecting plate, and spacer upper end is fixed on by gland 6
On connecting plate.
Preferably, it is located on the outside of connecting shaft between the universal ball bearing top and bottom and vehicle body hanger and is equipped with limit
Block 7.
Preferably, the gland is fixed on connecting plate by bolt 8.
The protection scope of the utility model is not limited to the above embodiments, it is clear that those skilled in the art can be right
The utility model carries out various changes and deformation without departing from the scope of the utility model and spirit.If these changes and deformation
Belong in the range of the claims of the present invention and its equivalent technology, then the intention of the utility model also include these change and
Including deformation.
