Description

Technical Field

[0001] The utility model belongs to the technical field of overhead crane equipment, and particularly relates to a fixture auxiliary opening and closing device. Background Technique

[0002] An overhead crane is an important special equipment in industrial production and plays an important role in product transportation and maintenance hoisting during the production process of iron and steel enterprises. In medium and heavy plate production, it is necessary to use an overhead crane to hoist slab billets, and the hoisting between the overhead crane and the slab billets is realized through a fixture. Whether it is unloading the vehicle when the billets are put into storage or hoisting the billets into the furnace, it is necessary to use the fixture to assist the overhead crane to achieve it.

[0003] At present, the clamping arms of the fixture control jaws used are in a diamond structure, and the four corner points of the diamond are hinged; when the upper and lower corner points of the diamond are close to each other, the fixture jaws open; when the upper and lower corner points of the diamond are far from each other, the fixture jaws shrink; when the fixture is not in use, the fixture jaws need to be opened wide, and the opened fixture jaws are fixed by an opener.

[0004] The opener adopts a mechanical structure and is divided into upper and lower parts. The opener is closed after the two parts are inserted and buckled. After the opener vibrates up and down, the two parts are separated and the opener is opened; the upper and lower parts of the opener are respectively fixedly installed at the upper and lower corner points of the fixture clamping arms. After the fixture jaws are opened to a certain angle, the opener is buckled and connected, and then the opening angle of the fixture jaws is fixed.

[0005] When hoisting is required, the fixture jaws are aligned with the hoisting material. During the contact process between the fixture and the material, the fixture is vibrated, the opener is separated, and the fixture jaws shrink with the hoisting process to clamp the hoisted object.

[0006] If the opener cannot be closed in time after the fixture is not in use, the fixture jaws will shrink to the minimum state, affecting the next use. At present, after a failure occurs, it is necessary for the staff to manually jack up the fixture to make the opener buckle. During this process, it is necessary for multiple people to prepare tools on the ground for processing, which has potential safety hazards and is time-consuming and laborious. Content of the Utility Model

[0007] In view of the problems existing in the prior art, the utility model provides a fixture auxiliary opening and closing device.

[0008] The utility model is realized as follows. A fixture auxiliary opening and closing device includes a base. A vertical column is vertically arranged upward on the top surface of the base. A cross beam is arranged on the top surface of the vertical column, and the cross beam is perpendicular to the vertical column; a level is also arranged on the top surface of the base, and the level is used to display the levelness of the base; adjusting feet are arranged on the bottom surface of the base, and the adjusting feet are used to adjust the levelness of the base.

[0009] Further, the height of the upright post after supporting the cross beam is higher than the depth of the fixture opening.

[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0020] Refer to Figures 1 to 3 , a fixture auxiliary opening and closing device, including a base 1, and the base 1 is made of a steel plate of Q235B material, and the specification dimensions are 60 mm in thickness, 2000 mm in width, and 2500 mm in length respectively. The base 1 plays a role in stably supporting the whole device, avoids the hidden danger of the device tipping over during the process of handling the fixture failure, and can be used on various bottom surfaces.

[0021] On the top surface of the base 1, four vertical columns 2 are fully welded and connected vertically upward. The four columns 2 are arranged at equal intervals in a straight line on the top surface of the base 1. The columns 2 are square steel or H-shaped steel made of steel plates, with a specification size of 120mm x 120mm, and the steel plate material is Q235B. The four columns 2 are the main load-bearing parts in the device, which can prevent the clamping arm of the clamp from shifting to the other side of the device, resulting in position deviation and affecting the fastening of the opener 8.

[0022] On the top surface of the column 2, a cross beam 3 is fully welded and connected. The cross beam 3 is perpendicular to the four columns 2 at the same time; the height of the cross beam 3 erected by the columns 2 is higher than the opening depth of the clamp 6, to avoid the friction between the jaws of the clamp and the bottom surface before the opener 8 is fastened, which affects the fastening of the opener 8; the four columns 2 support the bottom surface of the cross beam 3 at the same time to increase the anti-deformation strength of the cross beam 3. The cross beam 3 is square steel made of steel plates, with a specification size of 200mm x 200mm, and the steel plate material is Q235B. The top cross beam 3 is in direct contact with the clamp. The cross beam 3 enters the jaws of the clamp to support the structure inside the jaws. Along with the gradual descent of the overhead crane, the clamp contracts in the longitudinal stretching direction and opens horizontally, and the opener 8 is fastened, and the opening angle of the jaws of the clamp is fixed.

[0023] Furthermore, a spirit level 5 is also arranged on the top surface of the base 1. The spirit level 5 is a bubble spirit level, and the spirit level 5 is used to display the levelness of the base 1. The bubble spirit level is simple to operate and does not require power supply. As long as it is placed on the surface of the base 1 and the position of the bubble is observed, the levelness can be judged, which reduces the manufacturing cost of the device.

[0024] Furthermore, adjusting feet 4 are arranged on the bottom surface of the base 1. There are four adjusting feet 4, which are respectively located at the four corners of the bottom surface of the base 1; the adjusting feet 4 are used to adjust the levelness of the base 1.

[0025] Furthermore, the bottom surface of the column 2 is welded to a horizontal base 7. The horizontal base 7 is made of a rectangular steel plate; the horizontal base 7 is welded to the top surface of the base 1 to increase the connection strength between the column 2 and the base 1, reduce the pressure of the column 2 on the base 1, and improve the service life of the base 1.

[0026] The working principle of the present utility model is as follows:

[0027] First, firmly weld the bottom plate, columns and cross beam together, then place the bottom plate on a flat ground, adjust the adjusting feet to make the device level and keep it stable without shaking;

[0028] Then use the overhead crane to slowly lift the clamp that the opener 8 cannot fasten, and align the jaws of the clamp with the top frame cross beam;

[0029] Finally, align the fixture jaws with the crossbeam of the top frame, and then slowly lower the fixture so that it can be placed stably on the crossbeam of the top frame. Open the fixture jaws until the opener 8 is latched; after the opener 8 is latched, keep the fixture jaws stationary. At this time, lift the fixture smoothly and it can be used.

[0030] The materials and processing costs of this device are relatively low, effectively shortening the fault handling time and reducing the time for handling production anomalies. Before using this device, it took 40 minutes to handle the stretching and opening fault of the pretreatment fixture once. After using this device, it only takes 5 minutes to handle the fault, and the single parking time is reduced by 35 minutes, which is significantly helpful for improving production efficiency.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
