Description

Benchmark roof beam telescopic bracket for anchor rod anti-pulling test
Technical Field
The utility model relates to the technical field of reference beam supports, in particular to a reference beam telescopic support for an anchor rod pulling resistance test.
Background
In the anchor rod anti-pulling test, the reference beam is required to be supported, the existing reference beam supporting device cannot stretch out and draw back, the reference beam cannot be supported rapidly and effectively when the uneven ground is encountered, and the detection efficiency is reduced. In addition, the device is clumsy and inefficient and is very inconvenient to carry.
CN201822006723.9 an auxiliary support structure of benchmark roof beam, including a pair of supporting screw rod, threaded connection in a pair of vertical setting screw sleeve on the supporting screw rod, rotate connect in the rotation axle sleeve at screw sleeve top and be fixed in a pair of rotation axle sleeve keep away from the plummer of supporting screw rod one side, have and guarantee benchmark roof beam stable in structure, reduce detection error's advantage. The technical problem that the beam body is likely to deform and bend to influence the detection effect of the settlement amount due to the gravity and the environmental influence and the detection accuracy is reduced is solved. However, the device needs to be supported by a horizontal platform, and once the ground is uneven, the device cannot be firmly supported.
Disclosure of Invention
The utility model aims to provide a reference beam telescopic bracket for an anchor rod pulling resistance test, which can be used for telescopic adjustment and solves the problems that an existing device cannot quickly and effectively support a reference beam when encountering a land with uneven topography, and the detection efficiency is affected.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
a benchmark beam telescopic bracket for an anchor rod pulling test comprises two transverse support rods, two longitudinal telescopic rods respectively arranged on the two transverse support rods, and a support seat arranged between the two longitudinal telescopic rods;
the supporting seat is used for supporting the reference beam;
the longitudinal telescopic rod is used for adjusting the supporting height.
Further, the longitudinal telescopic rod comprises two threaded sleeves, two ends of the longitudinal telescopic rod are respectively sleeved on screws in the two threaded sleeves, and the directions of threads in the two threaded sleeves are opposite.
Further, a rotary handle is fixed on the screw rod.
Further, the two threaded sleeves are respectively connected with the supporting seat and the transverse supporting rod in a rotating mode through bolts.
Further, a connecting rod is arranged between the two transverse supporting rods.
Furthermore, the lower end of the transverse supporting rod is provided with a universal wheel, and the universal wheel is provided with a locking piece.
The reference beam telescopic bracket for the anchor rod anti-pulling test has the beneficial effects that:
the length of the longitudinal telescopic rods is adjustable, the reference beams with different heights are adjusted and supported, the two longitudinal telescopic rods can be adjusted to different lengths, the horizontal support of uneven terrain is ensured, the plurality of supports are combined and used for supporting the reference beams together, the telescopic arrangement of the supports is adjusted at will according to the length of the reference beams, and the convenience in transportation and high portability are ensured.
Drawings
FIG. 1 is a schematic side view of a plurality of brackets according to an embodiment of the present utility model;
FIG. 2 is a schematic diagram of a front view of a bracket according to an embodiment of the present utility model;
in the figure:
the device comprises a transverse supporting rod 1, a supporting seat 2, a reference beam 3, a connecting rod 4, a universal wheel 5, a threaded sleeve 6, a screw rod 7 and a rotary handle 8.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1:
referring to fig. 1-2, a reference beam telescopic bracket for an anchor rod pulling test comprises two transverse support rods 1, two longitudinal telescopic rods respectively arranged on the two transverse support rods 1, and a support seat 2 arranged between the two longitudinal telescopic rods; the supporting seat 2 is used for supporting the reference beam 3; the longitudinal telescopic rod is used for adjusting the supporting height.
A connecting rod 4 is arranged between the two transverse supporting rods. The support is used for connecting the transverse supporting rods 1 on two sides into a whole, the universal wheels 5 are arranged at the lower ends of the transverse supporting rods 1, the universal wheels 5 are arranged to facilitate movement of the support, locking pieces are arranged on the universal wheels 5, and the locking pieces can ensure that the support is stable in the supporting process.
The longitudinal telescopic rod comprises two threaded sleeves 6, two ends of the longitudinal telescopic rod are respectively sleeved with screw rods 7 in the two threaded sleeves 6, and the directions of threads in the two threaded sleeves 6 are opposite. A rotary handle 8 is fixed on the screw rod 7. Since the screw thread directions of the two screw thread sleeves 6 are opposite, the extension or shortening of the longitudinal telescopic rod can be controlled after the screw 7 is rotated. The two threaded sleeves 6 are respectively connected with the supporting seat 2 and the transverse supporting rod 1 in a rotating way through bolts, and after the bolts are screwed up, the angle fixation of the longitudinal telescopic rod can be ensured, and the supporting stability is ensured. When the length of the longitudinal telescopic rod needs to be adjusted, the bolts at the two ends of the threaded sleeve 6 are loosened, the supporting angle is changed while the length is changed, and after the adjustment is completed, the bolts are screwed, so that the support is stable.
When the movable support is used, the height of the reference beam is adjusted, the plurality of supports are arranged for supporting according to the length of the reference beam, and the movable support is convenient to move and carry after the movable support is used.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
