Abstract

The present invention provides a basket locking mechanism which can solve the technical problem that a gap is formed since an existing tank bottom opens outwards due to uneven stress. The basket locking mechanism comprises a tank body, a tank bottom, a traction hanging bracket, and main chains. The tank bottom comprises two tank bottom half shells distributed left and right. The tank bottom half shells are hingedly connected to a rotating support at the side of the tank body by means of rotating arms on the front and rear sides. The traction hanging bracket is separately connected to the two tank bottom half shells by means of two main chains. The basket locking mechanism further comprises locking plates, a locking pin, a guide pipe, and an auxiliary chain. The locking plates are mounted on the sides of the splicing end faces of the tank bottom half shells, a locking hole is formed in each locking plate, the locking pin is connected to the traction hanging bracket by means of the auxiliary chain, the locking pin is vertically provided in the guide pipe, and the guide pipe is mounted on the rotating support. The guide pipe is in a vertical shape and located above the splicing position after the two tank bottom half shells are closed. After the two tank bottom half shells are closed, the two locking plates are distributed up and down, and the locking holes and the locking pin are arranged in an opposite mode.

Description

A kind of material basket locking mechanism

technical field

The invention relates to material transportation equipment for metallurgical enterprises, in particular to a material basket, in particular to a material basket locking mechanism.

Background technique

The material basket used in metallurgical enterprises is composed of a tank body and a tank bottom. The tank bottom includes two half-shells distributed left and right that can be opened by an opening mechanism. The opening mechanism includes a traction hanger. The two tank bottom half shells are directly connected. When blanking, the traction hanger is lifted by driving, and then the chain pulls the two tank bottom half shells to lift upwards and open, and the scrap steel falls. When loading scrap steel or raw materials, due to the uneven force on the two tank bottom half shells, the tank bottom half shell on one side is easy to open outwards to form a gap, resulting in leakage of waste or raw materials.

technical problem

The invention provides a material basket locking mechanism, which can solve the technical problem that the existing tank bottom opens outward due to uneven force and forms a gap.

technical solution

Its technical solution is as follows: a material basket locking mechanism includes a tank body, a tank bottom, a traction hanger and a main chain, the tank bottom includes two tank bottom half-shells distributed left and right, and the tank bottom half-shell The rotating arms on the front and rear sides are hinged to the rotating support on the side of the tank body, and the traction hanger is respectively connected to the two tank bottom half shells through two main chains. It is characterized in that it also includes a locking plate and a locking pin , a guide pipe and an auxiliary chain, the locking plate is installed on one side of the splicing end face of the tank bottom half-shell, a locking hole is opened on the locking plate, and the locking pin is connected to the traction hanger through an auxiliary chain, so The locking pin is vertically arranged in the guide tube, and the guide tube is installed on the rotating bracket. The guide tube is in an upright shape and is located above the joint of the two tank bottom half-shells after closing. When the two tank bottom half-shells are closed, After the bottom half-shell is closed, the two locking plates are distributed up and down, and the locking hole and the locking pin are arranged facing each other.

Further, the upper part of the body of the locking pin is provided with a guide head, and the guide head is slidingly and guidingly matched with the guide tube.

Further, the lower part of the body of the locking pin is provided with a guide tail end, and the guide tail end is a tapered structure.

Further, when the bottom half-shell of the tank is opened, the locking pin is located in the guide tube.

Beneficial effect

The basket locking mechanism of the present invention locks the two tank bottom half-shells by inserting the locking pin into the locking plate, thereby preventing the tank bottom from opening outward due to uneven force. With the frame linkage, not only no additional power mechanism is needed, the cost is low, but also no manual operation is required, the locking action will not be forgotten, and the safety is good.

Description of drawings

Fig. 2 is a front structural schematic view of the basket locking mechanism of the present invention, wherein the bottom of the tank is in an open state. Fig. 3 is a structural schematic diagram of the cooperation between the guide tube and the locking pin of the present invention.

Embodiments of the present invention

As shown in Figures 1 to 3, a basket locking mechanism includes a tank body 1, a tank bottom 2, a traction hanger 3, a main chain 4, a locking plate 6, a locking pin 7 and an auxiliary chain 5, and the tank bottom 2 includes There are two tank bottom half-shells 2a distributed left and right. The tank bottom half-shells 2a are hinged with the rotating support 10 on the side of the tank body 1 through the rotating arms 9 and rotating shafts 11 on the front and rear sides, and the traction hanger 3 passes through two main chains 4. Connect with the two tank bottom half-shells 2a respectively. The locking plate 6 is installed on the splicing end surface 2b side of the two tank bottom half-shells 2a. There is a locking hole on the locking plate 6. The locking pin 7 is connected to the traction crane through the auxiliary chain 5. The frame 3 is connected, the locking pin 7 is erected in the guide tube 8, the guide tube 8 is installed on the rotating support 10, and the guide tube 8 (the guide tube is not shown in Fig. 1 and Fig. 2, please refer to Fig. 3) is erect shape and located above the joint of the two tank bottom half shells 2a after closing (the joint is the position where the joint end faces 2b of the two tank bottom half shells fit each other after the tank bottom is closed), when the two tank bottom half shells After 2a is closed, the two locking plates 6 are distributed up and down and the locking holes and the locking pins 7 are facing each other. When the tank bottom half shell 2a is opened, the locking pin 7 is located in the guide tube 8, ensuring that the locking pin 7 is always in the guide tube 8 during the opening and closing of the tank bottom, ensuring the effectiveness of the locking mechanism.

The upper part of the main body 7a of the locking pin is provided with a guide head 7b, and the guide head 7b and the guide pipe 8 slide and guide to cooperate. Preferably, the cross section of the guide head 7b and the cross section of the guide pipe are circular, and the lock pin 7 The lower part of the main body 7a is provided with a tapered guide tail end 7c. The setting of the guide head 7b can ensure that the guide pin is always in an upright state during the movement in the guide tube 8, preventing it from tilting.
