Abstract

The utility model relates to a multifunctional high-speed derrick in a hydraulic automatic lift type. A derrick body is composed of an upright post, a cross bar and an inclined bar. Guide wheels arranged on a sleeve frame take the surface of the internal angle of the upright post as a guide way. An overhead pulley assembly and a using gin pole are arranged on the sleeve frame, and a hydraulic lifting system composed of an oil cylinder, etc. is arranged below the sleeve frame. When a standard section is installed, an internal sleeve frame is lifted by a hydraulic piston, the assembled standard section on the ground is lifted by the using gin pole to the top surface of a building, and then the derrick is installed by an installing gin pole. When the derrick is installed to a specific height, closed-top channel steel connected with the internal sleeve frame is fixed. The utility model has the advantages of reasonable structure, good integral stability, safe construction, high conveying speed, high erecting height and strong lifting power.

Description

Mulitfunction high speed wellhead by hydraulic lift

The utility model relates to the steel headframe elevating mechanism in the high-building construction.

For the convenient material that promotes steel headframe must be arranged in this high-building construction.There is not self-hoisting unit of TQ 60/80 for solving traditional steel headframe, lifting is dangerous, the problem that security effectiveness is low, our company designs a kind of " self lift type high speed derrick elevating mechanism " (patent No. 94202105.3), it is in the middle of the column of the steel headframe that is made of column, cross bar, brace, dress jacking inner casing base frame, the lifting body that dress is made of jacking motor, jacking screw rod, jacking slew rate reducer in the mounting.Four jiaos of dresses of stock directive wheel is set up portion's structure stand above in jacking, and dress hangs and rises mechanism on the support.Improve work efficiency 6-8 doubly though this mechanism promotes building unit than traditional derrick, adopt the jacking mode of pushing up on the driven by motor screw rod, swung by the jacking frame because of jacking, not steady.Screw mandrel exposes the job site simultaneously, is difficult for protection.

The purpose of this utility model be intended to design a kind of more reasonable than former structure, resistance to overturning good, travelling speed is high, elevating capacity is strong, antenna height is high, easy installation and removal, self lift type multifunctional high speed derrick safe and reliable to operation.

The purpose of this utility model realizes in the following manner, hydraulic pressure self lift type multifunctional high speed derrick, the derrick body is made of four head tree angle steel 5, derrick cross bar 4, derrick brace 3, stock is positioned in the middle of the four root post angle steel in the jacking, four directive wheels 25 are respectively adorned at the four sides up and down, directive wheel 25 is a guided way with column angle steel interior angle, and the cover top of the trellis can be along the installation gin pole 14 of center of rotation 16 rotations in the jacking, and pulley 13, the rope made of hemp 12 can roll on the installation gin pole.Be equipped with on the column of stock in the jacking and use gin pole supporting base 17,18, use gin pole 21 to fix by becoming spoke wire rope 20 and supporting base, stock is divided into lifting body in the jacking, lifting body adopts hydraulic lifting mechanism, stock is provided with in the jacking, lower platform 8,2, a side of stock is provided with the Movable bracket 27 that there is hook 26 at two ends in jacking, carriage links to each other with the top rail 32 of stock in the jacking by hydraulic jack 6 pistons 11, two channel-section steels 10 that bind are arranged at stock top in the jacking, the channel-section steel that binds links to each other with interior stock, and the both sides, bottom respectively are provided with one the fixing block 1 of pin.

The utility model is described in detail in detail with reference to the accompanying drawings.

Fig. 6 the utility model contour structures schematic diagram.

With reference to accompanying drawing, when using the utility model jacking, in jacking, adorn directive wheel 25 earlier on the stock 9, then jacking hydraulic system and jacking operating desk are placed on the upper mounting plate 8.Refill hydraulic jack 6, hydraulic piston 11, connect oil pipe.Dress is installed gin pole 14 at last, uses gin pole 21, top sheave frame 30 and associated sheaves 13,19,23,29,31.

On installation gin pole pulley 13, wear the one 4 " rope made of hemp 12.Install the 0.5T hoist engine on ground, hoist engine wire rope 22 is walked around the pulley 19,23 that uses on the gin pole 21, connect suspension hook 24, with suspension hook the winding shaft frame member is carried to the building top layer, again carriage hook 26 is hung over (see figure 4) on the standard knot gusset piece 33, operating hydraulically operated then station 7 control sticks, top on the hydraulic piston 11, make stroke of stock jacking, put down stock bottom block 1, make block hang over one the joint standard knot gusset piece on 33(see Fig. 3), at this moment, carriage suspension hook and block just in time be in the lifting standard knot height the position.Then with suspension hook will be at the good half standard knot derrick except that upper beam of installation on ground, carry to the building top layer, use instead again and gin pole 14 is installed is suspended on next standard knot and installs.

After treating that a joint standard knot installs, operating hydraulically operated again station, oil return is regained carriage, and carriage hook 26 is suspended on the joint standard knot gusset piece, and puts down block 1, begins to prepare the installation of next joint standard knot again.Treat derrick installation to specified altitude, the channel-section steel 10 that binds of will linking to each other with interior stock again is fixed on four steel posts of derrick, and puts down block, regains carriage and hangs up properly, and promptly finishes the lift-rising work of standard knot.

When the work for the treatment of finishes the dismounting standard knot, the operating hydraulically operated action bars of elder generation, carriage 27 is descended, hook 26 is suspended on the gusset piece of next joint standard knot, the bind connecting bolt of 9 of interior stocks of channel-section steel 10 and jacking of dismounting, again block 1 is bearing on the gusset piece of next standard knot, can will goes up a standard knot and dismantle.Repeat above process, can finish the dismounting of whole derrick.

Derrick installation is to specified altitude, and behind the fixed sealing inverted draw cut steel, according to need of work, and peace top sheave frame 30, top sheave 29,31 on the channel-section steel that binds, hanging basket hoisting line 28 is walked around under the top sheave and is connect hanging basket, with the vertical relevant constructional materials of handling up of hoist engine, hanging basket.

When the installing/dismounting standard knot, installation personnel stands on two platforms of stock in the jacking and works, and is convenient and safe.When standard knot needs lift-rising, need not remove top sheave, use gin pole, gin pole be installed, installation, convenient disassembly, efficient height.

The utility model is rational in infrastructure, and the hydraulic lifting mode is adopted in jacking, and resistance to overturning is good, and elevating capacity is strong, travelling speed is fast, antenna height is high, can reduce construction costs.It is narrow that the utility model also is adapted at the place, the construction plant of tower crane should not be installed use.
