Description
Technical Field
The utility model relates to a metallurgical belted steel handles production line, in particular to blanking hole protector for the protection in slitter edge coiling machine equipment outlet side blanking hole behind the circle shear provides the safety guarantee for operating personnel and the maintainer at blanking hole regional work, walking.
Background
At present, in a metallurgical strip steel processing production line, a blanking pit with a length and a width of about 2.5m multiplied by 1.2m and a slope slideway is generally arranged at the outlet side of a slitter edge coiling machine. The scrap edge wire of the strip steel sheared by the circle shear falls down from the scrap edge coiling machine after being coiled into a coil by the scrap edge coiling machine, and then slides into a scrap box in a pit on the outer side of the unit through a slope through a discharge opening. Most of discharge openings of a blanking pit of an existing strip steel processing unit are open, an operator can only stand on supporting channel steel between the two discharge openings to operate or process other various accidents, and therefore operation is very dangerous, and the operator can step empty from the supporting channel steel and slide into the blanking pit with a slope slideway carelessly.
Disclosure of Invention
In order to solve the safety problem in slitter edge coiler outlet side, blanking hole discharge opening region, the utility model provides a blanking hole protector lets operation or maintainer can work or walk at blanking hole region safely.
The utility model provides a technical scheme that its main problems adopted is: the top in blanking hole, the transmission side of unit and operation side respectively set up a platform that can move, move in good time through two moving platform, spill or cover the discharge opening to protect the discharge opening in blanking hole. The specific method comprises the following steps: the shape of the opening of the original blanking pit is unchanged, and the retaining wall section steel and the supporting channel steel around the original blanking pit are replaced by the fixing frame. Long groove steel on the front side and the rear side of the fixed frame is used as a track of the mobile platform, and two mobile platforms which are provided with wheels and can move left and right are arranged above the fixed frame; two cylinders are arranged below the moving platform, the cylinders drive the moving platform to move on the rail, when a piston rod of each cylinder retracts, the moving platform leaves the discharge opening, and the discharge opening leaks out for discharging; when the piston rod extends out, the movable platform advances to cover the discharge opening of the blanking pit, and people stand on the movable platform to work or walk safely.
The beneficial results of the utility model are that, there is protective device above the discharge opening of blanking hole, provides the safety guarantee for operating personnel and the maintainer of work or walking in the discharge opening region, has effectively prevented to appear the incident in the discharge opening region.

The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a plan view of a mount and a blanking pit foundation.
Fig. 2 is a configuration diagram of the mobile platform.
Fig. 3 is an installation and usage diagram of the blanking pit protecting device of the present invention.
In the figure: 1. the device comprises a fixed frame, 2 parts of long channel steel, 3 parts of short channel steel, 4 parts of supporting channel steel, 5 parts of a moving platform, 6 parts of a bracket, 7 parts of wheels, 8 parts of a cover plate, 9 parts of a pin, 10 parts of a connecting plate, 11 parts of an air cylinder, 12 parts of a joint and 13 parts of an air cylinder pit cover plate.
Detailed Description
In fig. 1 and 3, the blanking pit is a concrete foundation with a slope blanking slideway, and the blanking pit protection device is mainly used for safety protection of a blanking pit area and comprises a left moving platform 5, a right moving platform 5, two cylinders 11 and a fixed frame 1. The fixing frame 1 is a frame structure formed by welding two long groove steels 2, two short channel steels 3 and a supporting channel steel 4, and is pre-embedded in a blanking pit foundation by taking the central line of a unit as the center. A supporting channel steel 4 in the middle of the fixing frame 1 divides the fixing frame 1 into two rectangular square holes which are used as discharge openings of the slitter edge rolls; the long groove steel 2 at the front and back sides of the fixed frame 1 is used as a walking track of the mobile platform 5.
In fig. 2, the movable platform 5 is assembled by components such as a bracket 6, wheels 7, a cover plate 8, a pin 9, a connector 10, and the like. The cover plate 8 is placed on the bracket 6, the cover plate 8 and the bracket 6 are not welded, and the cover plate is a detachable movable cover plate and can be taken down from the bracket 6 at any time, so that the equipment is convenient to install and overhaul. The wheel 7 is internally provided with a bearing, so that the wheel 7 can rotate on the long groove steel 2 of the fixed frame 1 more flexibly. The pin 9 is welded under the cover plate 8, and the cover plate 8 is positioned on the bracket 6 through the pin 9, so that the cover plate 8 is prevented from shaking on the bracket 6 or sliding off the bracket 6 greatly in the process of rapid movement of the mobile platform 5.
In the embodiment shown in fig. 3, the left and right moving platforms 5 are respectively placed on the fixed frame 1, the two cylinders 11 are symmetrically placed left and right, and are installed and fixed below the two moving platforms 5 and outside the discharge opening, and a cylinder pit cover plate 13 is laid above the cylinders 11 to protect the cylinders and facilitate the walking. The moving platform 5 is connected with the air cylinder 11 through the connecting plate 10 and the joint 12, and the air cylinder 11 on the left side is connected with the moving platform on the left side to drive the moving platform 5 on the left side; the right cylinder 11 is connected with the right moving platform to drive the right moving platform 5. The cylinder 11 drives the moving platform 5 to do reciprocating linear motion on the fixed frame 1 to form two independent movable platforms which can move, and the two movable platforms can move simultaneously or one of the two movable platforms moves independently according to requirements to leak or cover the discharge opening. When the movable platform 5 covers the discharge opening, the equipment is operated or overhauled by standing on the movable platform 5; when the movable platform 5 is far away from the discharge opening, the discharge opening is leaked, and the slitter edge rolls are discharged.
