An anchor tensile test support device for horizontal tensile testing machine

Abstract

The invention discloses an anchor tensile test supporting device suitable for a horizontal tensile testing machine, which comprises a mobile base, a first lifting device, a second lifting device, a positioning fixture and a distance measuring device. The mobile base is a cuboid, the upper plane of the mobile base is provided with two parallel T-shaped grooves in the length direction, and the lower plane is equipped with a plurality of rollers; the first lifting device and the second lifting device are sequentially one high and one low, The left and right isolation is fixedly connected to the T-shaped slot of the mobile base through T-shaped bolts; the positioning fixture is a "J"-shaped plate-shaped structure, and the hook is placed on the anchor to be tested on the first lifting device and the second lifting device. An anchor tip below the fluke end; the distance measuring device is placed on the shackle end of the anchor to be tested. The invention can realize the tensile tests of different types of anchors on the universal horizontal tensile testing machine, and can also realize the automatic and continuous measurement of the distance between the marked points, which reduces the cost of the anchor tensile test and improves the efficiency of the anchor tensile test.

Description

technical field [0001] The invention relates to a supporting device, in particular to an anchor tensile test supporting device for a horizontal tensile testing machine, and belongs to the technical field of horizontal tensile test auxiliary devices. Background technique [0002] With the development of larger ships, the performance of port tugboats is getting better and better, and the conditions of tugboats equipped in ports are getting more and more perfect. Captains and pilots mainly rely on tugboats to assist in completing berthing and unberthing operations, while anchors are the An important tool in maneuvering is an essential element for safe operation of ships, and anchors are widely used in ship maneuvering, especially small and medium-sized ships. The use of anchors in ship maneuvering can be roughly divided into three categories: mooring anchors, anchors for auxiliary maneuvers in the port and anchors for emergency maneuvering. Therefore, whether the strength of t...

Problems solved by technology

Due to the different angles and shapes of various anchors, it is necessary to prefabricate anchor pits of different specifications, and this set of test devices can only be used for anchor tests, so the utilization rate of the device is low and the test cost is high; At the same time, measure the distance from the end of the anchor rod to the anchor tip, so it is necessary to mark the anchor rod and the anchor tip before the test, and manually measure the distance between the marked points before and after the test, so the test efficiency is low and the labor intensity is low. Big

[0004] The Chinese patent application No. 200820238937.2 discloses a "Hydraulic Horizontal Tensile Testing Machine", which mainly includes a frame, a tractor, a hydraulic cylinder, a pulley, a tension rod, and a rolling support. Carry out mechanical experiments, but due to the special requirements of anchor experiments, this device cannot directly conduct experiments on anchors

This device fixes the shackle of the anchor to be tested on the ear plate of the horizontal tie rod, the anchor claw hooks the working platform, and applies a load to it through the hydraulic cylinder, but this device cannot guarantee that the force is accurately applied to the anchor to be tested. On the other hand, it is not easy to measure the distance from the end of the anchor rod to the anchor tip, and the range of experimental objects of this device is relatively small, and the utilization rate is low
