Background technique

Prior art, the traditional primary chassis member preclude the use of the post elevating mechanism fixed on the ground, provided with guide rails on the column, the lifting carriage can slide on the rail, the carriage is provided with support frame for the boom bracket means . When the boom elevating mechanism limits the carrying capacity of the support arm, and therefore, this kind of structure is difficult to meet the requirements of automated conveyor member under the chassis of the heavy vehicle body. SUMMARY

The present invention aims to overcome the above shortcomings, providing a means to meet the requirements of automated conveyor member under the chassis of the heavy vehicle body, reliable performance, ease of automation, productivity can be improved under heavy chassis parts lifting mechanism.

According to the aspect of the present invention provides, under the use of heavy lifting mechanism chassis member is fixed on the ground around the post, right and left guide rails are fixed to the left and right columns, the left and right sliding guide frame are connected to the left and right slide, wherein the carriage is left mounting bracket, the movable bracket with the fixing bracket and the slider are connected by a linear rails, the linear rails connected to the fixed bracket, slide on the linear slide sleeve, the cylinder is fixed to the fixing bracket, movable end of the cylinder an active connection with the supporting frame, mounted above the left and right columns are top frame, a drive motor mounted on the top shelf, the drive sprocket and the driven sprocket, the drive motor connected to the shaft and drive sprockets, four lifting chain on the sprocket connected to the counterweight tray,

The four lifting chain and two chains and the other end connected to the left side of the carriage, the other end of the chain to bypass two carriage driven sprocket connected to the right side.

Prior art and the present invention has the following advantages:

The present invention is simple, compact and reasonable; Automation chassis meet the heavy vehicle body member

Delivery requirements, reliable performance, ease of automation, production efficiency can be improved. BRIEF DESCRIPTION

Figure 1 is a front view of the new overall configuration utility.

3 FIG. 2 is a side view of an overall configuration utility novel structure. 3, FIG. 4 a side view of the new and carriage uprights present invention. detailed description

Hereinbelow, the present invention will be further described in conjunction with the accompanying drawings in Example:

As shown in FIG. 1 ~, includes 4: left and right columns L, left and right guide 2, the left and right sliding frame 3, the top

Frame 4, the driving motor 5, a drive sprocket 6, the drive shaft 7, 8 driven sprocket, the chain 9, the IO counterweight holder, fastening bracket 11, the cylinder 12, linear rail 13, the movable support frame 14, the front support block 15 and the rear support block 16, the slider 17 and the like.

The present invention mainly uses the left and right columns 1 is fixed to the ground, the right and left guide rails 2 are fixed around the column 1, about the left and right sliding guide frame 3 are slidably connected to 2, characterized in that the fixing bracket mounted on the left side of the carriage 311 , active support frame 14 is connected to the slider 17, the fixed bracket 11 and the linear slide 13 is connected, the linear slide rail 17 on sleeve 13, the cylinder 12 is fixed to the fixing bracket 11, the cylinder 12 and the movable end movable supporting connecting frame 14, left and right columns 1 are mounted above the upper frame 4, a drive motor 5 is mounted on the top frame 4, a drive sprocket 8 and a driven sprocket 6, the drive motor 5 drive shaft 7 is connected with the drive sprocket 6, sprocket four lifting chain on one end connected to the IO counterweight tray; four lifting chains in two lifting chain 9 is connected to the left end of the carriage 3, the other ends of the two lifting chain around the driven chain 9 the carriage 8 and the right wheel 3 is connected.

Operation of the movable support frame 14 is pushed by the cylinder 12 relative to the movable support frame 13 slidably implemented on a linear slide rail 17 on 14.

The working process of the invention:

When the member reaches the lower point of the heavy vehicle body, the support frame 3 activity (left and right) of the carriage 14 has been pushed to a final position of the cylinder 12, to start the drive motor 5 (left and right) of the carriage 3 is lifted support block before the rear support 15 and the block 16 are respectively supported to the vehicle body front and rear tires, spreader open (left and right) of the carriage 3 is lowered to the final bit body onto the top side of the machine waits pallet, the movable support frame 14 of the cylinder 12 is reset, (left and right) of the carriage 3 can be increased, the cylinder 12 pushing the movable support frame 14 to the final position, can take over a vehicle body. Since the fixing bracket and the support bracket activities are rectangular tube frame structure, so bearing capacity, appearance and structural rules to facilitate automation.
