Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that after the anchor rod is pulled out and tested, the wedge-shaped block will clamp the anchor rod in the fixed sleeve in an interference manner, making it extremely difficult to disassemble. Hit the fixed sleeve with a hammer to separate the fixed sleeve from the wedge block, but it is difficult to knock because of the small size of the fixed sleeve, so there is a defect that it is inconvenient to dismantle the bolt pulling equipment

Embodiment Construction

[0036] The following is attached Figure 1-5 The application is described in further detail.

[0037] The embodiment of the present application discloses a bolt pulling device.

[0038] refer to figure 1 and figure 2 , an anchor rod 9 is pre-embedded on the wall, and the anchor rod 9 protrudes from the inside of the wall and is perpendicular to the wall. A kind of anchor rod drawing equipment includes a jack 1 sleeved on the anchor rod 9, used for The hydraulic pump 11 for the oil supply of the jack 1, the fixing device 2 for fixing the anchor rod 9, and the backing plate 8 between the jack 1 and the wall. When carrying out the pull-out test on the anchor rod 9, the backing plate 8, the jack 1 and the fixing device 2 are set on the anchor rod 9 in sequence, so that one end of the jack 1 is in contact with the backing plate 8, and the other end of the jack 1 is in contact with the fixing device. 2 butt. Then, oil is supplied to the jack 1 through the hydraulic pump 11, an...

Abstract

An anchor rod drawing device of the present invention comprises a jack sleeving an anchor rod and an oil hydraulic pump used for supplying oil to the jack, a fixing device used for being fixed to the anchor rod is arranged at the side, away from a wall body, of the jack, and the fixing device comprises a fixing sleeve and a plurality of wedge-shaped blocks arranged in the fixing sleeve. The inner wall of the fixing sleeve gradually inclines inwards along the direction towards the jack, the anchor rod is clamped in the fixing sleeve through the wedge blocks, and a connecting sleeve sleeves the side wall of the jack; one end of the connecting sleeve is fixedly connected with the fixing sleeve, the other end of the connecting sleeve is connected with an abutting plate, and a push rod is hinged to the side wall of the jack. The push rod is obliquely arranged towards the abutting plate along the jack and abuts against the abutting plate, a trigger rod used for pushing the push rod to close is arranged on the side wall of the connecting sleeve in a penetrating manner, and the trigger rod is connected with the connecting sleeve in a sliding manner. According to the present invention, the workers can disassemble the anchor rod drawing device conveniently.

Description

technical field [0001] The present application relates to the field of bolt pretensioning equipment, in particular to a bolt pulling equipment. Background technique [0002] Anchor pulling equipment is a necessary on-site testing instrument for quality inspection units. Anchor pulling equipment is mainly used to detect the anchoring force of various anchors, steel bars and other anchors. [0003] The bolt pulling equipment is composed of a hydraulic pump, a jack, an intelligent digital display pressure gauge, and a high-pressure oil pipe with a quick connector. The jack is hollow and self-resetting, and the side of the jack away from the wall is provided with a fixing device for fixing with the anchor. , the fixing device includes a fixed sleeve and a plurality of wedge-shaped blocks arranged in the fixed sleeve. The inner wall of the fixed sleeve is gradually inclined to the center along the direction of the jack, and the wedge-shaped blocks clamp the anchor rod in the fix...
