Abstract
The invention relates to a clamping device. A rail clamping device comprises two rail clamps and two rollers, wherein the two rail clamps embrace each other oppositely; the two rail clamps are connected through a connecting shaft; roll shafts of the rollers are fixedly connected with the rail clamps. The rail clamping device can not only move along with a walking device, but also play anti-sliding and guiding roles, and is safe, reliable, convenient and practical.
Description
Technical field
The present invention relates to a kind of holding device.
Background technology
Excavator swing arm is welded by four principal welds of four block plate mats.For guaranteeing weldquality and welding process, in production, often with positioner, change the locus of workpiece, one end of swing arm is fixed, the swing arm other end rotates adjusts position of weld.During the asynchronous lifting of workpiece, boot thereupon parallel motion is safe and reliable when guaranteeing the work of boot running gear, avoids the lateral tilt that causes due to unstability, on walker, relevant safety device---rail clamping device must be set.
Traditional rail clamping device, rail tongsrail clamp is installed on the hardware of walking underframe, jaws can clamp in rail level both sides or clamp the web position at rail, rail tongsrail clamp shown in Fig. 1 is to be clipped in web position, the 1st, the side frame column of road wheel, the 2nd, adapter shaft, rail clamping device is comprised of rail tongsrail clamp 4 and bolt 3 etc.When running gear is parked, tight a bolt 3, make rail tongsrail clamp tightly clamp rail 5.In actual production process, be to coordinate the needs of position of weld, boot is often in adjusting and mobile status, so the position in parking for a long time.
Summary of the invention
The present invention aims to provide a kind of rail clamping device that is applicable to boot adjustment and mobile status.
Rail clamping device of the present invention, is characterized in that comprising two rail tongsrail clamps and two rollers, and two rail tongsrail clamp shapes are relatively embraces and shape, between two rail tongsrail clamps, by adapter shaft, is connected, and the roller bearing of roller is fixedly connected with rail tongsrail clamp.
Preferably, in roller, be provided with bearing and axle sleeve.
Rail clamping device of the present invention can move with running gear, can play anti-skidding and directional tagging again, safe and reliable, is convenient to practicality.
Accompanying drawing explanation
Fig. 1 is the part sectional view of traditional rail clamping device.
Fig. 2 is the part sectional view of rail clamping device of the present invention.
The specific embodiment
Embodiment mono-
As shown in Figure 1, rail clamping device of the present invention, comprises two rail tongsrail clamps 4 and two rollers 6, two rail tongsrail clamp 4 shapes are relatively embraces and shape, between two rail tongsrail clamps 4, by adapter shaft, be connected, the roller bearing of roller 6 is fixedly connected with rail tongsrail clamp 4, is provided with bearing 7 and axle sleeve 8 in roller 6.
Rail clamping device of the present invention is like this by the rail tongsrail clamp 4 near rail 5 parts, and change cliding friction is friction of rolling.And bearing 7 and axle sleeve 8 are installed, during use, make axle sleeve 8 and rail 5 rail level both sides leave adjusting play.Make rail clamping device can coordinate boot in actual production process often in adjusting and mobile state.
Claims (2)
