Description

Technical Field

[0001] This utility model relates to the field of engineering testing equipment technology, specifically a simple anchor bolt pull-out instrument. Background Technology

[0002] The anchor pull-out tester is mainly used to test the anchoring force of various anchor bolts, rebars, and other anchor bodies. The anchor pull-out tester consists of a manual pump, hydraulic cylinder, intelligent digital pressure gauge, high-pressure oil pipe with quick connector, reaction ring, anchor, adapter, and portable case. During use, the reaction ring, hydraulic cylinder, anchor, and adapter need to be sequentially fitted onto the anchor bolt being tested. The intelligent digital pressure gauge can directly read the anchor bolt tension value and has peak hold, storage, and query functions, making it particularly suitable for field use. It is simple to operate and easy to learn and use.

[0003] A search revealed that CN221199189U discloses an anchor bolt pull-out device, comprising a base plate, a manual pump fixedly mounted on the top of the base plate, a pressure gauge fixedly mounted on the top of the base plate, a pressure rod mounted on the top of the manual pump, a fixing block fixedly mounted on the outer side of the pressure rod, and a fixing sleeve fixedly mounted on the outer side of the fixing block. This anchor bolt pull-out device, through the design of multiple clamping components, can effectively improve the overall clamping stability and prevent loosening. The second plug-in post penetrates the fixing box and the fixing plate, accommodating rebars of different sizes. The fixing sleeve and plug-in post are designed for plug-in installation, allowing for length variations. The handle is made of rubber to increase friction and prevent slippage when using the pressure rod.

[0004] However, the present invention requires workers to lay soil under the hand pump to keep the hand pump horizontal during use, which is inconvenient and cannot meet the needs of use. Therefore, a simplified anchor puller is proposed to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1 and Figure 2 A simple anchor bolt puller includes an anchor bolt puller body 1, which consists of a manual pump 101 and a pressure gauge 102 fixedly mounted on the upper surface of a base frame 105, a hydraulic cylinder 103 disposed outside the base frame 105, a pressure block 107 disposed above the manual pump 101, and a handle 104 fixedly mounted on one side of the pressure block 107. An oil supply pipe is detachably installed between the hydraulic cylinder 103 and the manual pump 101, and the hydraulic cylinder 103 and the manual pump 101 are connected through the oil supply pipe. An anti-slip sleeve 106 is fitted onto the outer surface of the end of the handle 104. The anti-slip sleeve 106 allows the user to better grip the handle 104 for operation.

[0027] It should be noted that during use, the manual pump 101 and the hydraulic cylinder 103 are interconnected via an oil supply pipe. The pressure gauge 102 is located in front of the manual pump 101 for easy observation of the pressure. Furthermore, the manual pump 101 and the hydraulic cylinder 17 are interconnected via an oil supply pipe, allowing oil to be transferred from the manual pump 101 to the hydraulic cylinder 103 for overall operation. The anchor bolt puller body 1 is a conventional device known in the prior art; therefore, its specific structural composition and working principle will not be elaborated upon further in this text.

[0028] Example 2:

[0029] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 Based on Embodiment 1, a support structure 2 is provided on the lower surface of the base frame 105. The support structure 2 includes a connecting plate 204 and a base plate 201 arranged vertically, a connector installed between the connecting plate 204 and the base plate 201, and an electric telescopic rod 205. The connecting plate 204 is installed on the lower surface of the base frame 105 by bolts. A positioning structure 3 for fixing the anchor bolt puller body 1 is provided on the side wall of the base plate 201. The positioning structure 3 consists of a mounting block 301, a handwheel 302, and an insertion rod 303. By rotating the handwheel, the insertion rod 303 is moved to insert into the ground, thereby fixing the anchor bolt puller body 1 and making it less prone to slippage during use.

[0030] Specifically, the connecting components include a hinge seat 202 fixedly installed on the upper surface of the base plate 201 and a hinge block 203 fixedly installed on the lower surface of the connecting plate 204 and rotatably connected to the hinge seat 202. Mounting seats 206 are hinged to both the upper and lower ends of the electric telescopic rod 205, and the electric telescopic rod 205 is mounted between the connecting plate 204 and the base plate 201 via the mounting seats 206. Activating the electric telescopic rod 205 allows adjustment of the base frame 105, enabling the anchor bolt puller body 1 to be adjusted to a horizontal position.

[0031] In this embodiment, there are two connectors, which are symmetrically arranged and form a triangle with the installation position of the electric telescopic rod 205. The top end of the insertion rod 303 is fixed to the lower surface of the handwheel 302, and the insertion rod 303 is threaded through the interior of the mounting block 301.

[0032] The system includes four positioning structures 3, which are fixedly installed at the four corners of the base plate 201. To better adjust the anchor bolt puller body 1 horizontally, a level can be installed on the inner bottom wall of the base frame 105. The support structure 2 is bolted to the lower surface of the base frame 105, facilitating subsequent disassembly and transportation.

[0033] By adopting the above technical solution, the following was achieved:

[0034] The working principle of the above embodiments is as follows:

[0035] In use, the support structure 2 is installed on the base frame 105. The insertion rod 303 is moved by turning the handwheel to insert it into the ground, thereby fixing the anchor bolt puller body 1 and making it less likely to slip during use. Then, the electric telescopic rod 205 is started to adjust the base frame 105 and adjust the anchor bolt puller body 1 to a horizontal position.

[0036] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control functions, and the existing publicly available power connection technologies are not described in detail in the text.
