Problems solved by technology

The disadvantages of this anchor puller are: 1. It cannot directly pull the anchor with the hook at the end, and the on-site inspection cannot randomly check the anchor, and can only detect the reserved anchor. It is inconvenient to use, because of the use of reserved bolts, the pulling force of the bolts cannot be fully grasped, and thus the project quality cannot be guaranteed
2. There is no anchor creep measurement mechanism, and it is impossible to grasp the displacement of the anchor when the anchor is pulled out
3. There are defects in the design of the working anchor and the anchor clip, that is, it is difficult to disassemble after unloading, which brings inconvenience to the on-site operation
4. Since the working anchor is difficult to disassemble, only rough methods can be used on site, resulting in shortened service life of the puller

Embodiment Construction

[0044] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 An anchor rod puller for a frame beam on a roadbed slope is shown, including a jacking device 2, a bolt buckle frame 3 and an anchor plate 4; the fixed end of the jacking device 2 abuts on the roadbed slope 12 , the moving end of the jacking device 2 is connected to the anchor rod buckle frame 3, the anchor plate 4 is installed in the anchor rod pull frame 3, and the anchor plate 4 is provided with an anchor rod for the subgrade slope frame beam. 10 passes through the fastening hole 4-1, and two clips 11 for clamping the frame beam anchor rod 10 of the roadbed side slope are installed in the fastening hole 4-1. In this embodiment, it is preferred that the jacking device 2 is a hydraulic jack, wherein the fixed end of the jacking device 2 is the casing of the hydraulic jack, and the moving end of the jacking device 2 is a hydraulic jack big piston.

[0045] When in use, the hydraulic jac...

Abstract

The invention discloses a roadbed slope frame girder anchor rod drawing instrument which comprises an ejection device, an anchor rod buckling-pulling support and an anchor plate. The fixed end of the ejection device abuts against a roadbed slope, the movable end of the ejection device is connected with the anchor rod buckling-pulling support, the anchor plate is installed in the anchor rod buckling-pulling support, a clamping mounting hole where a roadbed slope frame girder anchor rod passes is formed in the anchor plate, and two clamping sheets for clamping the roadbed slope frame girder anchor rod are installed in the clamping mounting hole. According to the roadbed slope frame girder anchor rod drawing instrument, the roadbed slope frame girder anchor rod can be directly drawn, the anchor rod can be casually inspected at random, and the detection capacity can be greatly improved.

Description

technical field [0001] The invention relates to a pulling device, in particular to a roadbed side slope frame beam bolt puller. Background technique [0002] At present, for the detection of anchor rods of frame beams on subgrade slopes, the bolt pullers used all use a through-hole jack and a ring-shaped working anchor combination for pulling. It needs to reserve the anchor rods of the subgrade slope frame beams to be tested in advance. The disadvantages of this anchor puller are: 1. It cannot directly pull the anchor with the hook at the end, and the on-site inspection cannot randomly check the anchor, and can only detect the reserved anchor. It is inconvenient to get up, and due to the use of reserved bolts, the pulling force of the bolts cannot be fully grasped, and thus the project quality cannot be guaranteed. 2. There is no anchor rod creep measurement mechanism, and it is impossible to grasp the displacement of the anchor rod when the anchor rod is pulled out. 3. T...
