Description

Intelligent Short Exposed Anchor Puller

technical field

The invention relates to intelligent detection equipment, in particular to an intelligent short exposed bolt puller.

Background technique

Pull-out force testing of engineering anchors (cables), planting bars, spikes, etc., quantitative prestressing or pull-out work, if the exposed end is too short, common pulling instruments and equipment are helpless. The exposed ends of anchor rods (cables) and planting bars in normal engineering are all about 10cm. If the existing hollow jack is used for pulling, various methods must be used to lengthen them before implementation. Generally, it is necessary to reserve about 30cm for the exposed ends to implement pulling. pull. It is also because of this that random spot checks cannot be realized during the quality inspection of anchor rods (cables) and planting bars. A large part of the construction units, taking advantage of the disadvantage that the length of the exposed end must be reserved for the inspection, cut corners and materials are rampant, and the traditional sampling inspection has lost its meaning. The construction quality of anchor rods (cables) and planting bars is one of the important conditions to ensure the quality of the project. Realizing random sampling inspection is a necessary means to deter jerry building.

Contents of the invention

The purpose of the present invention is to provide an intelligent short-exposed anchor puller that can perform pull-out tests on anchor rods (cables) and planting bars with insufficient reserved length, so as to better control the quality of the project.

The intelligent short-exposed bolt puller of the present invention includes a hydraulic jack, a hydraulic cylinder, a two-way adjustable hydraulic pump, an oil inlet pipe, an oil return pipe, an anchorage, and an intelligent control host. It is characterized in that three hydraulic jacks of the same specification are The axes are evenly distributed at an angle of 120° each. Each individual hydraulic jack is fixedly connected by a fixed rod, a stress rod and an oil pipe. The middle structural support ring on the central axis passes through three stress rods and three hydraulic The jack is fixedly connected; the conical anchorage bracket coaxial with the middle structural support ring is fixedly connected with three hydraulic jacks respectively through three fixed rods, and the hydraulic jacks are connected through oil pipes; the anchorage is placed on the conical anchorage bracket Inside, the clips are placed in the anchor to form a complete clamping and pulling structure. By adjusting the thickness and size of the clips, rapid pull-out tests can be performed on different types of short exposed anchors; each hydraulic jack There are independent adjustment top plates on the top of the top plate, and leveling screws are installed on the independent adjustment top plates. The leveling screws are used to adjust the height of each hydraulic jack contacting the base surface. The conical anchor bracket protrudes beyond the hydraulic jack. The hydraulic jack is connected to the two-way adjustment hydraulic pump through the oil inlet pipe and the oil return pipe respectively, and the two-way adjustment hydraulic pump is connected to the hydraulic cylinder. The wireless oil pressure sensor is installed on the hydraulic cylinder, and the wireless oil pressure sensor is transmitted and intelligently controlled through Bluetooth wireless transmission. The hosts are connected and transmit data to the intelligent control host. The intelligent control host intelligently controls the oil pressure and loading level by controlling the two-way adjustment of the hydraulic pump. The intelligent control host operates the whole process of drawing steps and intelligently controls the numerical conditions in real time.

In the intelligent short-exposed bolt puller of the present invention, three jacks with screw-rod adjustable top plates and conical anchor brackets are rigidly fixedly connected to a triangular support with good stability and light weight. Place the anchor in the conical anchor bracket, clamp the anchor rod to be tested by the anchor clip, start the hydraulic pump to lift the jack, so that the conical anchor clamps the anchor rod (cable) to be tested, and install it The displacement test device can continue to pressurize, and it can be transmitted to the wireless host through the wireless pressure sensor and the wireless displacement sensor, and the loading amount and the pulling displacement amount can be displayed until the pulling reaches the test requirements. After the drawing is completed, adjust the control valve of the oil circuit and return the oil to unload.

The intelligent short-exposed anchor puller of the present invention can well solve the problem that the traditional anchor (cable) drawing method has insufficient reservation for the anchor (cable), which leads to the failure of random sampling inspection of the anchor, and avoids cutting corners. construction quality accidents. At the same time, the instrument can also realize automatic measurement, data storage, data upload management, etc. through wireless transmission technology, which is intuitive, efficient, safe, and convenient.
