Abstract
The utility model discloses a locking device for a guide plate of a steel pipe hot mill, and relates to a steel pipe hot mill. The locking device solves the technical problems that the conventional hydraulic cylinder locking device is complicated in structure, poor in working reliability and high in cost. The locking device for the guide plate of the steel pipe hot mill is characterized in that a right guide plate slanted plane and a left guide plate slanted plane are respectively arranged on two side surfaces of the guide plate, a guide plate rack is provided with a guide plate rack slanted plane corresponding to the right guide plate slanted plane, the guide plate rack is connected with a locking lever by a pin shaft, a locking lever slanted plane corresponding to the left guide plate slanted plane is arranged at the upper end of the locking lever, the guide plate is arranged on the guide plate rack, the right guide plate slanted plane and the guide plate rack slanted plane are matched, the left guide plate slanted plane and the locking lever slanted plane are matched, and a slanted wedge is inserted into a space formed by the guide plate rack and the locking lever. The locking device is used for the steel pipe hot mill, and has the advantages of being simple in structure, reliable to lock and low in cost.
Description
Technical field
The utility model relates to the Steel Pipe Heat milling train, particularly a kind of locking device of Steel Pipe Heat milling train guide plate.
Background technology
In various Steel Pipe Heat milling trains, a kind of instrument---guide plate is arranged, changing product specification or guide plate may wear to when affecting product quality, often need to change guide plate, guide plate need to be fixed on the rolling mill guide frame in the time of work, guide plate will be locked this moment, be fixed into one with the guide plate frame.
Used guide plate locking device is hydraulic locking cylinder at present, relies on the hydraulic lock in the hydraulic control system to realize locking.
The shortcoming of prior art: complex structure requires installing space large; Fluid pressure line, hydraulic lock are leaked sometimes, and it is unreliable to work; The numerous parts relevant with locking all needs to order spare part, causes cost of investment to increase.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of Steel Pipe Heat milling train guide plate locking device is provided, and solves traditional hydraulic locking cylinder device, complex structure, the technical problem that functional reliability is poor, cost is high.
The utility model is achieved through the following technical solutions:
A kind of Steel Pipe Heat milling train guide plate locking device, comprise: the rolling mill guide frame of resting guide, it is characterized in that: the two sides of described guide plate are respectively equipped with guide plate right tilted surface and guide plate left tilted surface, described guide plate sets up the guide plate frame inclined-plane corresponding with described guide plate right tilted surface, described guide plate frame is connected with the locking lever with bearing pin, the upper end of described locking lever is provided with the locking lever inclined-plane corresponding with described guide plate left tilted surface, described guide plate places on the described guide plate frame, and described guide plate right tilted surface is cooperated with described guide plate frame inclined-plane, described guide plate left tilted surface is cooperated with described locking lever inclined-plane, leave the space that wedge is set between the lower end of described locking lever and the described guide plate frame, the spatial interpolation that described guide plate frame and described locking lever form enters wedge.
Further, the angle of wedge of described wedge is less than angle of friction.
Further, the I wearing plate is set up on the surface that the lower end of described locking lever contacts with described wedge, and described locking lever is set up the II wearing plate on the inclined-plane.
The utility model compared with prior art owing to be provided with the inclined-plane in the two sides of guide plate, the guide plate frame also is provided with corresponding inclined-plane; The guide plate frame is connected with the locking lever with bearing pin; The guide plate frame enters wedge with the spatial interpolation that the locking lever forms.Along with the insertion of wedge, the locking lever rotates around bearing pin, forces the inclined-plane, upper end of locking lever to press guide plate, thereby makes guide plate locking.The utility model is used for the Steel Pipe Heat milling train, has simple in structure, reliable lock, advantage that cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is the B-B profile of Fig. 2.
The utility model is further described by preferred embodiment below in conjunction with accompanying drawing
The specific embodiment
Such as Fig. 1,2, shown in 3, a kind of Steel Pipe Heat milling train guide plate locking device, by locking lever 1, bearing pin 2, wedge 3, guide plate 4, guide plate frame 5, I wearing plate 6 and II wearing plate 7 form, the two sides of described guide plate 4 are respectively equipped with guide plate right tilted surface A and guide plate left tilted surface B, described guide plate frame 5 is provided with the guide plate frame inclined-plane A0 corresponding with described guide plate right tilted surface A, described guide plate frame 5 usefulness bearing pins 2 are connected with locking lever 1, the upper end of described locking lever 1 is provided with the locking lever inclined-plane B0 corresponding with described guide plate left tilted surface B, described guide plate 4 places on the described guide plate frame 5, and described guide plate right tilted surface A is cooperated with described guide plate frame inclined-plane A0, described guide plate left tilted surface B is cooperated with described locking lever inclined-plane B0, leave the space that wedge is set between the lower end of described locking lever 1 and the described guide plate frame 5, described guide plate frame 5 enters wedge 3 with the spatial interpolation that described locking lever 1 forms.
As shown in Figure 3, the angle of wedge a of described wedge 3 can guarantee that wedge does not skid off less than angle of friction after installing.
Shown in Fig. 2,3, I wearing plate 6 is set up with the surface that described wedge 3 contacts in the lower end of described locking lever 1, sets up II wearing plate 7 on the described locking lever inclined-plane B0.Can improve service life, reduce spare part quantity, reduce maintenance cost.
The utility model installation steps are as follows:
1, I wearing plate 6 and II wearing plate 7 are screwed on locking lever 1;
2, the above-mentioned assembly that assembles is connected on the guide plate frame 5 with bearing pin 2;
3, guide plate 4 is placed on the guide plate frame 5, require the right tilted surface A of guide plate 4 corresponding with the guide plate frame inclined-plane A0 of guide plate frame 5;
4, wedge 3 is inserted in the space of guide plate frame 5 and 1 formation of locking lever, and firmly strike dead;
When 5, needing to change guide plate 4, in the opposite direction wedge 3 is pounded out, unclamped guide plate 4.
The utility model also can be used for other identical operating modes.
