Abstract
The utility model relates to a tower-crane attached-frame device, which comprises U-shaped welding parts and a connecting part and is formed by abutting and connecting the two identical U-shaped welding parts; each U-shaped welding part is formed by combining and welding a long-slot steel beam (1) and two short-slot steel beams (2); a clamping device (5) is arranged on each U-shaped welding part, and the clamping device comprises a movable framework (5.1) which is clamped on the short-slot steel beams, a clamping bolt (5.2) and a fixed baffle plate (5.3) which is welded on the short-slot steel beams; the fixed position of the movable framework is controlled by adopting the clamping bolt, and the abutting of the two U-shaped welding parts is realized by respectively connecting through two connecting plates (3) and high-strength bolts (4); the clamping devices (5) are positioned at the same side when the two U-shaped welding parts are abutted and connected; and the fixed position of the movable framework is controlled by the clamping bolt, and both ends at the bottom of one U-shaped welding part are respectively provided with an ear plate (6) connected with an attached supporting rod. The tower-crane attached-frame device has the advantages of high efficiency, low cost, good safety and reliability, less material dosage, light weight and convenience in installation.
Description
The utility model belongs to the indispensable device of vehicle for construction tower crane when exceeding the unattached height use, in order to connect body of the tower and building, to strengthen body of the tower rigidity, improves the body of the tower force-bearing situation, improves reliability of structure.
Background technology
At present, skyscraper is more and more, and the use of tower machine is highly also along with increasing, and when the setting height(from bottom) of tower crane surpasses the unattached height of permission, the wall-attaching equipment of some just must be installed according to designing requirement.Wall-attaching equipment can increase the rigidity of body of the tower effectively, improves the body of the tower force-bearing situation, thereby improves serviceability of structures.The mount structure that adheres to that existing use is more general generally has two kinds: one, framed structure adopts a U-shaped weldment and a girder steel to be formed by connecting with bearing pin, wherein the U-shaped weldment is by three girder steel assembly weldings that become the I font with the sheet material assembly welding, this measure is taken a lot of work, and expense is expected, efficient is low, cost of manufacture is high, and the U-shaped weldment is too heavy when mounted, must use the auxiliary installation of hanging device, the clamping of this kind structure generally adopts bolt to clamp, though can adjust the clamping degree, but area of contact is little, easily cause the distortion of body of the tower main chord surface local, and bolt quantity is many; They are two years old, adopt two U-shaped weldments to connect by high strength bolt, the clamping mode of this structure generally is to be clamped by the part with body of the tower main chord outside face direct contact, if exist to make error would adhere to frame and the clamping of body of the tower unreliable, the reliability of wall-attaching equipment also just reduces greatly, has potential safety hazard.
Summary of the invention
Adhere to defective and the deficiency that mount structure exists in order to overcome above-mentioned existing tower crane, the utility model provides a kind of and has helped enhancing productivity, reducing cost of manufacture, and installs and uses easy, the novel frame apparatus that adheres to of failure-free.
The technical scheme that the utility model addresses the above problem is: a kind of tower crane adheres to frame apparatus, comprises U-shaped weldment and attaching parts, and the utility model adopts two identical U-shaped weldment butt joints to be formed by connecting; Each U-shaped weldment is made of an elongated slot girder steel and two short channel beam Combination Welding; Each U-shaped weldment is provided with a fixing device, and this fixing device is made up of the fixed dam that is stuck in movable frame, the fastening bolt on the short channel beam and be welded on the short channel beam; Two identical U-shaped weldment butt joints are to connect with high strength bolt by two connecting panels; Fixing device was positioned at the same side when two U-shaped weldment butt joints connected; The fixed position of movable frame is by the fastening bolt adjusting control on the fixing device, and two ends, a U-shaped weldment bottom respectively are provided with one and connect brace bar attached otic placode therein.Fixing device adopts fixed dam can prevent that movable frame from coming off from girder steel under off working state.For from fact improving the efficient manufacture, reducing production costs, the utility model has been done corresponding improvement on materials and clamping mode, and girder steel pastes the sealing plate by channel-section steel to be formed, clamps action and is then finished by fastening bolt promotion movable frame.
The elongated slot girder steel of each U-shaped weldment of the utility model and short channel beam paste the sealing plate by channel-section steel to be formed, and this compares with adopting sheet material assembly welding scheme, has shortened production time greatly, has simplified manufacture craft, enhances productivity greatly and cost of manufacture.Respectively have a cover to clamp device on each U-shaped weldment, when guaranteeing to install before and after the U-shaped weldment every can be separately and the body of the tower clamping; The moving track of movable frame is by two block plate weld togethers, totally two compositions; Fixing device is made up of the fixed dam that is stuck in slidably movable frame, the fastening bolt on the short channel beam upper and lower surface and be welded on the short channel beam, after must earlier movable frame being placed the relevant position during making, fixed dam on recombinant, the welding groove girder steel, fixed dam are in order to prevent that movable frame from coming off from short channel beam under off working state; Adhere to frame and do not have other three directions of fixing device then by arranging that two blocks of vertical each other steel plates contact with the two sides of body of the tower main chord.By the position of adjusting fastening bolt control movable frame and the clamping degree of adhering to frame, guarantee that all directions all also clamp with the body of the tower closed contact.With the body of the tower contact position be surface of steel plate, area of contact strengthens, and has increased its reliable clamping degree.The gap of controlling two U-shaped weldments during making is between 6～8mm, and is fastening with the high strength bolt connection when installing and using, and do not have steel plate vertical each other on other three directions of fixing device like this and just can guarantee and the body of the tower closed contact.Fixing device must be arranged in the same direction of the Combination Welding part of two U-shapeds.
The beneficial effects of the utility model are, compare with the version of generally using at present, and the utility model is made easier, production efficiency height, cost are low, install easily easy, safer, stablize, have more hommization, need not hanging device and also can finish installation.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further specified.
