Abstract
A kind of well lid residual deformation experiment displacement meter adjustable fixing device is related to field of road detection, for well lid residual deformation experimental test.Comprising being made up of three magnetic brackets, each magnetic bracket is made up of the device magnetic force block, connecting rod, expansion link and the connector between them, and three magnetic brackets are commonly connected on a ball adapter, forms the present apparatus.The utility model provides a kind of device for the fixation of displacement meter in the experiment of well lid residual deformation, with good stability, is provided simultaneously with position adjustment function, can adapt to the change of certain limit inner plane position, significantly improves test efficiency.
Description
Technical field
The present apparatus is applied to field of road detection, is particularly well-suited to the experiment of well lid residual deformation measure.
Background technology
Well lid residual deformation value is an important parameter of well lid performance indications, and well lid is placed on into experimental rig during experiment
Jack on, the upward jacking of jack is provided with displacement meter above well lid, and displacement can be read by displacement meter during jacking
The flexible value of meter.In conventional method, usually using a magnetic bracket come fixed displacement meter, displacement meter stability is excessively poor,
It is difficult to make displacement meter be in vertical direction, and because well lid model is more, the bars position and spacing set on its well lid are not yet
Equally, displacement meter needs to withstand on floor.Accordingly, it would be desirable to adjust the position of displacement meter regularly, typically move at present
Whole magnetic bracket is readjusted, less efficient.
The content of the invention：
The device is included with lower member：(1) magnetic force block, (2) sleeve coupler, (3) horizontal brace rod, the connection of (4) L-shaped
Device, (5) vertical connecting rod, (6) ball adapter, (7) expansion link, (8) cylindrical hole ball adapter.
A cylindrical hole, insertion and positioning for displacement meter 9 are carried in the middle of cylindrical hole ball adapter；Cylindrical hole is spherical
Connector has three joints, and the expansion link with three magnetic brackets is attached respectively, is organized into an entirety, forms this dress
Put.Each magnetic bracket includes magnetic force block, sleeve coupler, horizontal brace rod, L-shaped connector, vertical connecting rod, spherical connection
Device and expansion link.
Magnetic force block 1, sets magnetic switch；The one end of horizontal brace rod 3 is connected by sleeve coupler 2 with magnetic force block 1, another
End is connected with L-shaped connector 4；
L-shaped connector has two jointings, and angle is 90 ° between two jointings, respectively with horizontal brace rod 3 and
Vertical connecting rod 5 is attached；The vertical connecting rod other end is connected on ball adapter 6.
The one end of expansion link 7 is connected in spherical connection, and the other end is connected to cylindrical hole ball adapter 8, and expansion link can be with
Adjustment length, ball adapter and cylindrical hole ball adapter can in the horizontal direction adjust angle, realize in certain limit
Position adjustments.
The utility model provides a kind of well lid residual deformation and tests displacement meter adjustable fixing device, and the device is by three
Individual magnetic bracket composition, consolidates very much, can be good at ensuring that displacement meter is in vertical state, while each magnetic bracket is provided with
Expansion link, expansion link can adjust length；Expansion link two ends are connected on ball adapter, it is ensured that can be at horizontal position adjustment angle
Degree.Because the length and angle of the device can be adjusted, therefore, the position of its central point can arbitrarily adjust within the specific limits
It is whole, meet the requirement of most all kinds of well lid models.
Brief description of the drawings
Fig. 1 the utility model schematic diagrames.
Fig. 2 the utility model uses schematic diagram.
Specific embodiment
(1) magnetic force block 1 is one block of magnet of rectangle, can there is setting magnetic switch, be can be very good when the switch is opened solid
It is scheduled on the landing slab of testing equipment device, magnetic force disappears after closing switch, can unload the present apparatus.
(2) one end of horizontal brace rod 3 is connected by sleeve coupler 2 with magnetic force block, and the other end is connected with L-shaped connector 4；
(3) L-shaped connector has two jointings, and angle is 90 ° between two jointings, respectively with horizontal brace rod
3 and vertical connecting rod 5 be attached.
(4) the vertical connecting rod other end is connected on ball adapter 6.
(5) one end of expansion link 7 is connected in spherical connection, and the other end is connected to cylindrical hole ball adapter 8, and expansion link can
With adjustment length, ball adapter and cylindrical hole ball adapter can in the horizontal direction adjust angle, realize certain limit
Interior position adjustments.
(6) cylindrical hole, insertion and positioning for displacement meter 9 are carried in the middle of cylindrical hole ball adapter；Cylindrical hole
Ball adapter has three joints, and the expansion link with three magnetic brackets is attached respectively, is organized into an entirety, is formed
The present apparatus.
Well lid is placed on the jack 11 of experimental rig 10 during experiment, the upward jacking of jack, in the top of well lid 12
It is provided with displacement meter.
