Abstract
The utility model discloses a pile driver slinging mechanism including an upright post, and a platform. The top part of the upright post is provided with a balance pulley block arranged in rectangle. The balance pulley block comprises a pulley block component. The slinging cable wire rounds the balance pulley block and connect a pore-forming device(7) and a movable pulley block(5) in the front and back of the upright post. The front end of the haulage rope of a hauling engine pulls the movable pulley block to move up and down through a fixed pulley block(2). The back side of the upright post is also fixed with a guiding mechanism which prevents the movable pulley block from wringing. Each of the two pulley block components corresponding to the back and front of the balance pulley block respectively passes through two slinging cable wires simultaneously. Adopt the utility model and round two cable wires simultaneously which improves the force of the slinging cable wire without increasing the number of the pulley. And the guiding wire rope of the movable pulley block replaces the prior steel tube guide rod which simplifies the structure of the whole machine, reduces the sole weight, ensures the using security, and improves the service life of the pile driver cable wire.
Description
Technical field
The utility model relates to a kind of building machinery, specifically refers to the derricking gear in the pile driver.
Background technology
The column of pile driver is the main load parts in the complete machine, for making the column front and back stressed identical, usually at the top of column the equalizer pulley group is installed, hoisting wirerope is walked around the equalizer pulley group, hole-forming device before the column and the running block behind the column are coupled together, can promote hole-forming device to the traction of running block by hoist engine thus.This hoisting way makes column not produce moment of flexure in the lifting process, is pure depression bar, improves the ability of pulling out that rises of stake machine greatly.The rectangular distribution of equalizer pulley group, a left side, a left side, back, the preceding right side, four right installation positions of back before forming, the last pulley assembly that is separately installed with in each installation position, this pulley assembly are a single groove pulley, and a preceding left side (right side) only passes through one hoisting wirerope to the pulley assembly on a left side, back (right side).The rear side of column also is welded with two steel pipe guide rods usually simultaneously, and running block can be slided up and down along guide rod, prevents the running block twisting.
Along with the stake machine is done bigger and bigger, for improving pulling force, the necessary overstriking of hoisting wirerope, if still adopt above-mentioned equalizer pulley group structure, then each equalizer pulley also has to strengthen thereupon, to prolong the application life of wire rope, so both strengthened the weight at stake machine column top, be difficult to guarantee the safety of wire rope again, the making of guide rod and installation are all cumbersome, thereby have increased the deadweight and the manufacturing cost of complete machine.
The utility model content
The purpose of this utility model is to provide that a kind of cost simple in structure is low, simple installation and pile driver derricking gear safe in utilization.
For achieving the above object, the utility model comprises the column of a machine, platform, the column top is equipped with the equalizer pulley group of rectangular distribution, this equalizer pulley group comprises the pulley assembly that is installed on the rectangle corner location, hoisting wirerope is walked around the equalizer pulley group, the hole-forming device and the running block that connect the column front and back, the pull rope front end of hoist engine moves up and down by fixed pulley group traction running block, the column rear side also is fixed with the guiding device that prevents the running block twisting, on two corresponding before and after above-mentioned equalizer pulley group pulley assemblies, simultaneously by two strands of hoisting wireropes.
The further measure of such scheme, each pulley assembly can be made up of by single groove pulley two of installation arranged side by side, also can only adopt a double grooved pulley.
Adopt the utility model structure, on a pulley assembly of equalizer pulley group, walk around two strand steel wire ropes simultaneously, when not strengthening diameter of pulley, improved the stressed of hoisting wirerope, the guiding cable wire of running block has replaced original two steel pipe guide rods simultaneously, make the safety that complete machine structure is simplified, deadweight has ensured use when reducing, improve the application life of stake machine, also reduced the difficulty of construction and installation processes.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the coiling schematic diagram of wire rope in the utility model;
Fig. 3 is the sectional view of equalizer pulley.
The specific embodiment
Referring to accompanying drawing 1.The utility model comprises column 8, the platform 1 of a machine, column the place ahead is a hole-forming device 7, be fixed with fixed pulley group 2 on the platform at its rear, there is running block 5 top of fixed pulley group, the column top is equipped with the equalizer pulley group, and hoisting wirerope is walked around the equalizer pulley group and connected into aperture apparatus 7 and running block 5.The column rear side also has a guiding cable wire 3, and this guiding cable wire upper end is fixed on the column top, and the lower end is fixed on the platform by screw-button.Be with slip pipe 4 on the guiding cable wire, running block 5 is fixedlyed connected with slip pipe.
Referring to Fig. 2, the rectangular distribution of equalizer pulley group at column top, the position, four angles of corresponding rectangle is equipped with pulley assembly, this pulley assembly is double grooved pulley 6 (see figure 3)s, hoisting wirerope forms four strands on the equalizer pulley group, per two strands of hoisting wireropes are taken simultaneously in the double flute of the equalizer pulley 6 of two front and back correspondences, and front and back connect into aperture apparatus 7 and running block 5.
The pull rope front end of hoist engine is walked around fixed pulley group 2 and running block 5, moves up and down with traction running block 5.
During work, hoist engine twines or discharges pull rope, and running block 5 is moved up and down, and is drawing hoisting wirerope and is moving up and down, also passes through double grooved pulley 6 in twos, with lifting hole-forming device 7.
Double grooved pulley 6 in the foregoing description also can be substituted by two single groove pulleys of installing side by side.
Claims (5)
1, a kind of pile driver derricking gear, comprise column (8), platform (1), the column top is equipped with the equalizer pulley group of rectangular distribution, this equalizer pulley group comprises the pulley assembly that is installed on the rectangle corner location, hoisting wirerope is walked around the equalizer pulley group, the hole-forming device (7) and the running block (5) that connect the column front and back, the pull rope front end of hoist engine moves up and down by fixed pulley group (2) traction running block, the column rear side also is fixed with the guiding device that prevents the running block twisting, it is characterized in that: on two corresponding before and after above-mentioned equalizer pulley group pulley assemblies, each is simultaneously by two strands of hoisting wireropes.
