Description
Technical field
The utility model relates to tower machine technology field, refers in particular to a kind of crane arm lower edge frock holding device.
Background technology
Along with expanding economy, real estate industry more and more prevails, but the building in house but be unable to do without necessary apparatus---tower machine.The existence of tower machine decreases much unnecessary trouble to the people of the son that builds a house.In general tower machine can be divided into by the function of each several part: basis, tower body, jacking, turn round, hoist, the part such as counter-jib, crane arm, trolley, tower top, drivers' cab.Tower machine is installed needs foundation on the ground; Tower body is tower fuselage, is also the part raised; Jacking part is that tower machine can be raised; Swinging keeps tower machine can horizontally rotate above the waist; Lifting mechanism is used for heavy lift; Balance jib is holding torque balance; Elevator boom rack is exactly generally the part of the force of lifting heavy.Current derrick runway girder lower boom frock is generally that the frock that the crane arm lower boom of different model installs needs different is corresponding with it, and lower boom is when clamping, there is the shortcoming of distortion, drastically influence product size and welding quality, locating speed is slow, operating efficiency is on the low side.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of structure simple, swift to operate, locate reliable crane arm lower edge frock holding device.
For achieving the above object, technical scheme provided by the utility model is: a kind of crane arm lower edge frock holding device, it includes crossbeam, adjusting screw(rod), wherein, the rectangle framework that crossbeam is made up of some square tubes, four corners of rectangle framework are provided with vertically arranged adjusting screw(rod) sleeve, and adjusting screw(rod) is sleeved in adjusting screw(rod) sleeve, and its underpart is stretched out adjusting screw(rod) sleeve and formed feet; The length direction two ends of crossbeam respectively establish one group to hold out against assembly, the described assembly that holds out against includes fixed block, top board, clamp, clamping screw, and wherein, fixed block is vertically mounted on beam-end, top board one end is fixed on cross rail top, and the other end extends to crossbeam central horizontal and is connected with clamp upper end; Clamp lower end is unsettled formation screens vertically downward; Fixed block is provided with the clamping screw matched with this screens.
Be provided with Horizon bottom described adjusting screw(rod) and regulate foot pad.
The utility model, after employing such scheme, by rotating the adjusting bolt at two ends, can be raised crossbeam, make lower boom upwards near top board, ensures the flatness of plane on lower boom; Rotational lock bolt in addition, can make the outside of lower boom be close to locating surface, ensures the outer wide size of two lower booms.This programme have structure simple, swift to operate, locate reliable advantage.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1, crane arm lower edge frock holding device described in the present embodiment includes crossbeam 1, adjusting screw(rod) 2, wherein, the rectangle framework that crossbeam 1 is made up of some square tubes, four corners of rectangle framework are provided with vertically arranged adjusting screw(rod) sleeve 3, adjusting screw(rod) 2 is sleeved in adjusting screw(rod) sleeve 3, its underpart is stretched out adjusting screw(rod) sleeve 3 and is formed feet, is provided with Horizon and regulates foot pad 8 bottom described adjusting screw(rod); The length direction two ends of crossbeam 1 respectively establish one group to hold out against assembly, the described assembly that holds out against includes fixed block 4, top board 5, clamp 6, clamping screw 7, wherein, fixed block 4 is vertically mounted on crossbeam 1 end, top board 5 one end is fixed on crossbeam 1 top, and the other end extends to crossbeam 1 central horizontal and is connected with clamp 6 upper end; Clamp 6 lower end is unsettled formation screens vertically downward; Fixed block 4 is provided with the clamping screw 7 matched with this screens.This device, after employing such scheme, by rotating the adjusting bolt at two ends, can be raised crossbeam, make lower boom upwards near top board, ensures the flatness of plane on lower boom; Rotational lock bolt in addition, can make the outside of lower boom be close to locating surface, ensures the outer wide size of two lower booms.This programme have structure simple, swift to operate, locate reliable advantage.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
