Insert-type blade hanger deformation detector

Abstract

This utility model relates to the field of blade lifting device technology, and more particularly to a modular blade lifting device deformation detector. The modular blade lifting device deformation detector includes a rectangular base with an inner opening. A side channel is formed on one side wall of the base near the inner opening, and a slider is movably connected within the inner opening. In use, the user holds the handle and manipulates the base, placing two measuring plates on the side wall of the base at the two end walls of the lifting device. Rotating the screw drives the slider, causing it to move along the screw axis and change the position of the two sliders. When the two sliders approach each other, the measuring plates also approach and contact the end walls of the lifting device. At this point, pulling the base causes the measuring plates to slide along the long end wall of the lifting device. When the end wall of the lifting device is uneven due to deformation, the measuring plates are blocked, facilitating rapid measurement and identification of whether the lifting device has deformed, resulting in high efficiency.

Description

Technical Field

[0001] This utility model relates to the field of blade lifting device technology, and in particular to a modular blade lifting device deformation detector. Background Technology

[0002] After prolonged use or during transportation, blade lifting tools may deform, which can affect their subsequent safe use. Generally, a measuring device is used to inspect the lifting tool to detect whether deformation has occurred. This detector is used to detect whether lifting tools have deformed.

[0003] When inspecting blade lifting devices, a measuring tool is typically used to measure the end wall of the lifting device to check for deformation. However, because the lifting device has a certain size and a large surface area, multiple measurements at multiple points are required, resulting in a large amount of measurement work and making it neither fast nor convenient. Utility Model Content

[0004] The purpose of this invention is to provide a modular blade hanger deformation detector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular blade hanger deformation detector includes a rectangular base with an inner opening and a side channel on one side wall of the base near the inner opening. A slider is movably connected inside the inner opening, and a screw threadedly connected to the slider and rotatably connected to the base. A rectangular measuring piece is fixed to the side wall of the slider.

[0007] Preferably, a handle is fixed to the side wall of the base away from the side passage.

[0008] Preferably, the end wall of the measuring piece is provided with perforations at equal intervals.

[0009] Preferably, a cylindrical movable rod is movably connected inside the opening.

[0010] Preferably, a top seat is fixedly connected to the top wall of the movable rod.

[0011] Preferably, a spring is fixedly connected to the end wall of the top seat, and the other end of the spring is fixedly connected to the measuring piece.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. When using, hold the handle and operate the fixed base so that the two measuring plates on the side wall of the fixed base are placed at the two end walls of the spreader. At this time, rotate the screw to drive the slider, so that the slider moves along the screw axis and changes the position of the two sliders. When the two sliders are close, the measuring plates also move close and make contact with the end walls of the spreader. At this time, pull the fixed base to measure and make the measuring plates slide along the long end wall of the spreader. When the end wall of the spreader is deformed and uneven, the measuring plates will be blocked, which facilitates quick measurement and understanding whether the spreader has deformed, and is highly efficient.

[0014] 2. The movable rod is connected at the opening. Under the action of the spring force, the top seat and the movable rod move accordingly, so that the movable rod has force and moves towards the horizontal central axis of the fixed seat. When measuring the lifting device, if there is a dent or notch on the end wall of the lifting device, the end of the movable rod will automatically spring into the notch. At this time, the fixed seat is limited, which makes it easy to quickly identify the small notch and make the measurement more accurate. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution for a modular blade hanger deformation detector:

[0023] like Figure 1-4 As shown, the insert-type blade hanger deformation detector includes a rectangular base 1, an inner opening 3 inside the base 1, a side channel 4 on one side wall of the base 1 near the inner opening 3, a slider 5 movably connected inside the inner opening 3, a screw 6 threadedly connected to the slider 5 and rotatably connected to the base 1, and a rectangular measuring piece 7 fixed to the side wall of the slider 5.

[0024] A handle 2 is fixedly attached to the side wall of the fixed seat 1 away from the side passage 4;

[0025] The end wall of the measuring piece 7 is provided with equidistant openings 8, and a cylindrical movable rod 9 is movably connected inside the openings 8;

[0026] A top seat 10 is fixedly connected to the top wall of the movable rod 9, and a spring 11 is fixedly connected to the end wall of the top seat 10. The other end of the spring 11 is fixedly connected to the measuring piece 7.

[0027] Working principle:

[0028] The handle 2 on the side wall of the base 1 is convenient for the user to hold;

[0029] When in use, hold handle 2 and operate the fixed base 1 so that the two measuring pieces 7 on the side wall of the fixed base 1 are placed at the two end walls of the lifting device. At this time, rotate the screw 6 to drive the slider 5, so that the slider 5 moves along the axis of the screw 6 and changes the position of the two sliders 5. When the two sliders 5 are close, the measuring pieces 7 also move close and make contact with the end walls of the lifting device. At this time, pull the fixed base 1 to measure and make the measuring pieces 7 slide along the long end wall of the lifting device. When the end wall of the lifting device is deformed and uneven, the measuring pieces 7 will be blocked, which facilitates quick measurement and understanding whether the lifting device has deformed, and is highly efficient.

[0030] The two measuring pieces 7 form a clamping shape and can be inserted into the end wall of the lifting device and connected with the lifting device, making the measurement more time-saving and labor-saving;

[0031] The movable rod 9 is connected at the opening 8. Under the action of the spring 11, the top seat 10 and the movable rod 9 move accordingly, so that the movable rod 9 has force and moves towards the horizontal central axis of the fixed seat 1. When measuring the lifting device, if there is a dent or notch at the end wall of the lifting device, the end of the movable rod 9 will automatically spring into the notch. At this time, the fixed seat 1 is limited, which makes it easy to quickly identify the small notch and make the measurement more accurate.
