Abstract
The utility model discloses a kind of suspended shock damper, belong to Drilling derrick light fixture suspended shock damper, including：Mandrel, outer barrel, spring, connecting bolt, upper cross plate, lower cross plate, fixing bolt, connecting shaft, upper cross plate and lower cross plate are arranged between derrick panel, it is fixed on derrick panel by fixing bolt, fixing bolt is connected with mandrel by connecting shaft, damping spring is set on mandrel, and outer barrel coordinates with mandrel, and outer barrel is connected with connecting bolt, connecting bolt lower end is provided with screw thread, is connected with light fixture.The utility model, it is simple and compact for structure, it is connected firmly, consumption is slowed down by the spring set on mandrel due to the jerk produced during wellbore construction, suspended shock damper realizes the safety suspension of light fixture simultaneously.The problem of solution is one damping device of increase between derrick and light fixture fixing point, when light fixture is in suspension status, effectively reduces the vibrations that derrick passes to light fixture, makes being connected for light fixture safety and stability.
Description
Technical field
The suspended shock damper that the utility model is related to, specifically, the utility model is related to a kind of Drilling derrick light fixture
Suspended shock damper.
Background technology
During wellbore construction, drilling tool easily produces vibrations when rotated due to geologic structure, and drilling tool is produced
Vibrations be delivered on derrick, meanwhile, drilling equipment produce vibrations can also be delivered on derrick, both produce vibrations transmission
After on to derrick, light fixture is produced jerk, cause light fixture to damage, existing light fixture hang is directly to use in addition
Hook is suspended on derrick panel, and the jerk that wellbore construction is produced is directly delivered on light fixture, causes light fixture to damage, if
Safety inspection is not in place, is directly also easily caused the risk that light fixture generation is fallen with the mode of hook connection.Therefore, now needing one
Plant the suspended shock damper dedicated for Drilling derrick light fixture.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of damping dress suitable for the suspension of Drilling derrick light fixture
Put.
In order to solve the above-mentioned technical problem, the skill that a kind of Drilling derrick light fixture suspended shock damper of the utility model is used
Art scheme is：Including mandrel, outer barrel, spring, connecting bolt, upper cross plate, lower cross plate, fixing bolt, connecting shaft, the upper horizontal stroke
Plate, lower cross plate are fixed by fixing bolt and derrick panel, and the fixing bolt is connected with mandrel by connecting shaft, the mandrel
Spring is provided with core, the mandrel is arranged in outer barrel with spring, and the outer barrel lower end sets connecting bolt, the connection spiral shell
Bolt is connected with light fixture, by the spring being arranged on mandrel, stretches to slow down rushing for derrick vibrations using the physical characteristic of spring
The damage to light fixture is hit, the connecting bolt suspended lamp set by the connection of fixing bolt and mandrel and outer barrel lower end can
The light fixture that avoids loosely cause because being connected falls.
Using the technical solution of the utility model, following beneficial effect can be obtained：A kind of Drilling derrick of the utility model
Light fixture suspended shock damper, it is simple and compact for structure, it is connected firmly, can buffer derrick on Drilling derrick shook
The shock loading produced in journey, it is to avoid the damage of light fixture, while the degree that is connected firmly of light fixture and derrick can also be increased.Realize
Light fixture is fixedly secured effect.
Brief description of the drawings
Brief description is made to the mark in the content and figure expressed by this specification accompanying drawing below：Fig. 1 is this practicality
New structural representation；Mark in Fig. 1 for：1st, mandrel；2nd, outer barrel；3rd, spring；4th, connecting bolt；5th, upper cross plate；5-1、
Lower cross plate；6th, fixing bolt；6-1 connecting shafts.
Specific embodiment
Below against accompanying drawing 1, by the description to embodiment, to specific embodiment of the present utility model as involved by
The shape of each component, the mutual alignment between construction, each several part and annexation, the effect of each several part and operation principle etc. make into
The detailed description of one step.
It is structural representation of the present utility model as shown in Fig. 1, including：Mandrel（1）；Outer barrel（2）；Spring（3）；Connection
Bolt（4）；Upper cross plate（5）；Lower cross plate（5-1）；Fixing bolt（6）；Connecting shaft（6-1）.
As shown in figure 1, by the upper cross plate of this suspended shock damper（5）Lower cross plate（5-1）By fixing bolt（6）With derrick
Crossbeam is fixed, fixing bolt（6）It is connected with mandrel by connecting shaft, mandrel（1）Upper setting spring（3）, mandrel is arranged on outer barrel
（2）It is interior, outer barrel（2）Lower end sets connecting bolt（4）, connecting bolt（4）It is connected with light fixture by the screw thread of lower end, derrick is produced
Jerk load pass through mandrel（1）Pass to spring（3）, spring（3）The physical characteristic being had bears rigid shock
Lotus is converted into round elastic impact, spring（3）Elastic impact derrick is produced impact energy consumption differentiation so that quickly
Jerk load is reduced, weakened consuming up to impact and terminate within the extremely short time.
Suspended shock damper of the present utility model is used to reduce the impact energy between derrick and light fixture, in drilling process
Derrick is buffered consumption with the impact energy of light fixture, it is to avoid the jerk of lamp assembly is damaged, while realizing light fixture and derrick
The effect that is connected.
