Abstract
A support strengthening device for a tower crane attached frame comprises a special-shaped spacer, bolts, a fixed block, support arms and horizontal slide hole bolts. The overall fixed block as a main part is in a form of an angle iron. Connecting lugs are disposed on the lower portion of the fixed block. Each connecting lug is provided with a horizontal slide hole for correspondingly connecting with one support arm. Two same horizontal slide hole bolts are disposed in each horizontal slide hole. Four though holes provided with the bolts inside are arranged on two sides of the upper portion, which is connected with the special-shaped spacer through the bolts, of the fixed block. The fixed block is fixed on a main segment of a standard section through the four bolts and the special-shaped spacer. The support arms are assemblies welded by angle irons, steel pipes and steel plates. The support strengthening device is simple in overall structure, safe and convenient to assemble and use and reusable. By the support strengthening device, the attached frame can be supported firmly, action area of a jackscrew or a wedge on the standard section is increased, and accordingly, the standard section of a tower crane body can be protected effectively.
Description
Technical field
The utility model relates to construction hoisting machinery tower crane auxiliary device, relates in particular to tower crane and adheres to frame bracing reinforcement device.
Background technology
At present, orthodox method is carried out the tower machine when adhering to, or inserting steel pipe at standard knot first forms " well " cabinet frame, hangs fixingly with the iron wire colligation, will adhere to frame again and be placed on " well " cabinet frame; Perhaps directly adhering on the frame with the iron wire colligation, be suspended on the standard knot, this mode of adhering to frame that hangs with the iron wire colligation, under cover iron wire corrosion disconnects, and adheres to lower slide of frame, adheres to the system power transmission and is obstructed, the potential safety hazard of complete machine unstability.The jackscrew or the voussoir that adhere on the frame play the gap length that frame and standard knot are adhered in adjusting, to adhere to frame simultaneously and standard knot is fixed together, and form one, the jackscrew of present most of manufacturer production or voussoir action section are little, concentrate at the standard knot upward pressure, standard knot is deformed.
The utility model content
The purpose of this utility model is, overcome the deficiencies in the prior art part, provide a kind of tower crane to adhere to frame bracing reinforcement device, can overcome tradition and fixedly adhere to the frame shakiness with iron wire, the easily danger that disconnects of corrosion and adhering on the frame because jackscrew or the little strength of voussoir plane of action are concentrated the deficiency that the easy pinch of standard section main limb is out of shape, use steel pipe and angle steel to support and adhere to frame, can be fixed on securely on the standard knot by bolt, adhering to large gusset of increase between frame jackscrew or voussoir and the standard knot, increase the area of contact of jackscrew or voussoir and standard knot, thereby avoid the standard knot distortion.
Tower crane described in the utility model adheres to frame bracing reinforcement device, includes profiled spacer, bolt, fixed block, hold-down arm and horizontal slide opening bolt.Fixed block is main component of the present utility model, integral body is the form of angle steel, bottom at fixed block is provided with engaging lug, be provided with on the engaging lug with hold-down arm on the horizontal slide opening of corresponding connection usefulness, in horizontal slide opening, be provided with the horizontal slide opening bolt of two same form.The both sides, top of fixed block are provided with through hole, are provided with bolt in the through hole, and are bolted and are provided with profiled spacer.Specifically be drilled with four through holes on fixed block, be fixed on the standard section main limb by four bolts and special-shaped pad, hold-down arm is a fabricate block that forms with angle steel, steel pipe and Plate Welding.Steel pipe is used for rest and adheres to frame, and the original steel board of steel tube end part welding is used for stopping that adhering to frame outwards slides.The steel pipe other end is welded on the angle steel, is drilled with a long sliding hole on the angle steel, is installed on the fixed block with two bolts, is furnished with two hold-down arms on each bracing reinforcement device, and four one of bracing reinforcement installation compositions adhere to the frame support system.In view of the swash restriction of pawl and standard knot bolt of standard knot, the installation site height of this device can be slightly different, at this moment, unclamp the bolt on the steel plate, regulate the upper lower angle of hold-down arm, can realize the adjusting of hold-down arm level height, the height of eight hold-down arm steel pipes is adjusted in a level height after, standby tight bolt.Subsequently, install and adhere to frame, adjust jackscrew or voussoir and withstand on the angle steel of fixed block, thereby increased the area of effect, also just protected standard knot.
Tower crane described in the utility model adheres to frame bracing reinforcement device, and integral structure is simple, and assembling and use safe and convenient can be realized the turnover use.Use tower crane described in the utility model to adhere to frame bracing reinforcement device, can hold securely and adhere to frame, increase jackscrew or the active area of voussoir on standard knot, effectively protected tower-body standard section.
Description of drawings
Accompanying drawing 1 is the structural representation that tower crane described in the utility model adheres to frame bracing reinforcement device.1-profiled spacer, 2-bolt, 3-fixed block, 4-hold-down arm 5-horizontal slide opening bolt.
The specific embodiment
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: tower crane described in the utility model adheres to frame bracing reinforcement device, includes profiled spacer 1, bolt 2, fixed block 3, hold-down arm 4 and horizontal slide opening bolt 5.Fixed block 3 is main components of the present utility model, integral body is the form of angle steel, bottom at fixed block 3 is provided with engaging lug, be provided with on the engaging lug with hold-down arm 4 on the horizontal slide opening of corresponding connection usefulness, in horizontal slide opening, be provided with the horizontal slide opening bolt 5 of two same form.The both sides, top of fixed block 3 are provided with through hole, are provided with bolt 2 in the through hole, and are connected with profiled spacer 1 by bolt 2.Specifically be drilled with four through holes on fixed block 3, be fixed on the standard section main limb by four bolts 2 and special-shaped pad 1, hold-down arm 4 is fabricate blocks that form with angle steel, steel pipe and Plate Welding.Steel pipe is used for rest and adheres to frame, and the original steel board of steel tube end part welding is used for stopping that adhering to frame outwards slides.The steel pipe other end is welded on the angle steel, is drilled with a long sliding hole on the angle steel, is installed on the fixed block 3 with two bolts, is furnished with two hold-down arms on each bracing reinforcement device, and four one of bracing reinforcement installation compositions adhere to the frame support system.In view of the swash restriction of pawl and standard knot bolt of standard knot, the installation site height of this device can be slightly different, at this moment, unclamp the bolt on the steel plate, regulate the upper lower angle of hold-down arm, can realize the adjusting of hold-down arm level height, the height of eight hold-down arm steel pipes is adjusted in a level height after, standby tight bolt.Subsequently, install and adhere to frame, adjust jackscrew or voussoir and withstand on the angle steel of fixed block, thereby increased the area of effect, also just protected standard knot.Tower crane described in the utility model adheres to frame bracing reinforcement device, and integral structure is simple, and assembling and use safe and convenient can be realized the turnover use.Use tower crane described in the utility model to adhere to frame bracing reinforcement device, can hold securely and adhere to frame, increase jackscrew or the active area of voussoir on standard knot, effectively protected tower-body standard section.
