Description

The movable door frame of overhang roll pipemaking machine

The utility model relates to a kind of movable door frame of overhang roll pipemaking machine.

Existing a kind of its vertical columns of movable door frame (structure as shown in Figure 1) and Rotary cloumn that is used to produce the overhang roll pipemaking machine of cement sewer pipe is welded into by steel plate, and the mating face on the vertical columns is " second " shape, thereby the workload of processing and welding is bigger.

The purpose of this utility model is the movable door frame that a kind of overhang roll pipemaking machine will be provided, and its simple structure is easy to process.

Below in conjunction with drawings and Examples the utility model is specifically described.

Fig. 1 is that the dodge gate framework of existing overhang roll pipemaking machine is made schematic diagram.

Fig. 2 is the movable door frame of small-sized overhang roll pipemaking machine, and Fig. 3 is the A-A sectional view of Fig. 2, and Fig. 4 is the vertical view of Fig. 3.

Fig. 5 is the movable door frame of medium-sized overhang roll pipemaking machine.

With reference to Fig. 2-Fig. 4, the utility model comprises the Rotary cloumn 1 that is positioned at both sides, vertical columns 2 and the pivoted arm 3 that crosses on the column, the middle part of pivoted arm has main shaft bearing hole 4, one end hinge portion of pivoted arm is connected on the Rotary cloumn, it is characterized in that 1) inclined-plane of below, the other end of pivoted arm contacts with the inclined-plane above the vertical columns, the below of this contact surface 5 forward, the top is backward.2) be respectively equipped with on the taper pin socket 7 under the socket 6 and taper pin above the front side of the front side of pivoted arm the other end below and vertical columns, be plugged with a taper pin 8 in the upper and lower socket of taper pin, 3) back side top of vertical columns is provided with pivoted arm end location arc 9,4) vertical columns and Rotary cloumn be the garden pipe.

Movable door frame than existing overhang roll pipemaking machine, the utility model one is because vertical columns and Rotary cloumn are the garden pipe, and the mating face of pivoted arm end and vertical columns is the inclined-plane, therefore be convenient to processing, welding, the 2nd, owing to be respectively equipped with the upper and lower socket of taper pin and the taper pin through inserting the upper and lower socket of taper pin is located in the upper and lower side in the mating face of pivoted arm end and vertical columns, so the installing and locating precision of door frame is also higher.

The utility model course of work is as follows, close the door: when the user is enclosed within the pipe of cement moulding form on the main shaft, promote pivoted arm clockwise, make the end of main shaft insert dead eye successively, make oblique contact the above inclined-plane and the vertical columns of end below of pivoted arm, and, at last taper pin is inserted the upper and lower socket of taper pin by location arc stop.Open the door: the pipe of cement moulding on the overhang roll pipemaking machine, and after cement pipe die county hung main shaft, the user can transfer to cone pin, and pushes pivoted arm counterclockwise open, and the end of main shaft is broken away from, the dead eye of pivoted arm, unloaded the pipe of cement moulding form at last again.

Fig. 5 and Fig. 6 are another embodiment organigram.10 is Rotary cloumn among the figure, and 11 is vertical columns, and 12 is pivoted arm, and 13 is the main shaft bearing hole, and 14 is the inclined-plane of below, pivoted arm the other end, and 15 is socket on the taper pin, and 16 is socket under the taper pin, and 17 is taper pin, and 18 are location, pivoted arm end arc.

Claims

1. the movable door frame of an overhang roll pipemaking machine comprises the Rotary cloumn that is positioned at both sides, vertical columns and the pivoted arm that crosses on the column, and the middle part of pivoted arm has main bearing hole, and an end of pivoted arm is articulated on the Rotary cloumn, it is characterized in that:

1) inclined-plane of pivoted arm the other end below contacts with inclined-plane above the vertical columns, the below of this contact surface forward, the top backward,

2) be respectively equipped with on the taper pin socket under the socket and taper pin above the front side of the front side of pivoted arm the other end below and vertical columns, be plugged with a taper pin in the upper and lower socket of taper pin,

3) back side top of vertical columns is provided with location, pivoted arm end arc,

4) vertical columns and Rotary cloumn are the garden pipe.
