Abstract

The utility model discloses an adjustable attachment device of a tower crane. A rear beam, two longitudinal beams and a front beam define a square frame structure; an oblique supporting beam is arranged on a diagonal line in the device; the two ends of each longitudinal beam are connected by a pin shaft; four supporting rods on the periphery in the frame push against the edges of main angle steel on the two edges of a standard section; clamping plates are arranged at the two ends of the oblique supporting beam and mounted on the front beam and the rear beam respectively. According to the adjustable attachment device, the supporting rods are designed to be detachable, and grooves are formed in the two ends of each supporting rod and directly push against the main angle steel of the standard section, so that the effects of the horizontal supporting rods of the standard section are achieved; the clamping plates at the two ends of the oblique supporting beam are directly mounted on the front and rear beams by pin shafts, so that the clamping plates cannot be interfered with a tower body node plate and a stepping reinforcement plate when being mounted; when the adjustable attachment device is adopted, an attachment position can be adjusted in a certain range, so that the selection range of the attachment position of a building is expanded.

Description

Tower machine is adjustable attachment device

One, technical field

The utility model is the auxiliary facility of tower crane, is specifically related to a kind of standard knot and adheres to erecting device.

Two, background technology

The attachment device of tower machine standard knot is when tower machine surpasses free height, on tower machine tower body joint, adhesion frame is installed and connects Anchored Bar, is attached on building, to keep the resistance to overturning of tower machine.Attachment device can be installed multiple tracks, conventionally according to the height of building, determines.Attachment position and adhere to Dao Shuoyou producer and determine.Current conventional attachment device, is comprised of front-axle beam, the back rest, 2 longerons, 4 bracing frames and hound.Attachment position is in tower body when middle part joint, and after adhering to ring beam and installing, bracing frame is installed on four angles, withstands leading role's steel sharp corner, along diagonal, 1 diagonal ligament is installed, and tight with wedge piece Wedged, and ring beam and adhesion frame are firmly choked.Because there is horizontal web member at standard knot middle part, therefore can't make standard knot deform.But while installing in other positions of standard knot, the one, there is a gusset mobile jib inboard that standard knot is marked time, make bracing frame can with standard knot mobile jib on gusset plate and the gusset at the inboard place of marking time interfere and cannot install; The 2nd, place section does not have horizontal support, can cause the distortion of standard knot and adhesion frame when Xie Kuai Wedged is tight, tight Wu Fa Wedged, so it is adjustable to realize position.In actual use, the attachment position that often has user to propose to require to specifications, corresponding building does not have suitable attachment point, or cannot adhere at all, therefore proposes to adjust the requirement of attachment position.

Three, summary of the invention

In order to solve the adjustment problem of attachment device, the utility model provides a kind of tower machine adjustable attachment device, can require arrange according to building anchor point, by adjustments adhere to the position of frame on tower body joint with solve building anchor point change more, adhere to the problem that the installation site of frame on standard knot limited by anchor point.

The technical solution adopted in the utility model is: tower machine is adjustable attachment device encloses square bearer structure by the back rest, two longerons and front-axle beam, on device inner opposite angle line, there is raker beam, longeron of the present utility model two ends are that bearing pin connects, and have 4 struts to withstand on the limit of standard knot both sides leading role's steel in framework surrounding; There are clamping plate at raker beam two ends, and two ends clamping plate are arranged on respectively on front-axle beam and the back rest.

The utility model is designed to strut removable, the fluted immediate roof in strut two ends on standard section main angle steel, thereby played the effect of standard knot triatic stay.Raker beam two ends clamping plate are directly installed on forward and backward beam with bearing pin, while guaranteeing to install, do not interfere with tower body gusset plate and angle steel inner reinforced plate.

While adopting adjustable attachment device, attachment position can be adjusted within the specific limits, has increased the range of choice of building attachment position, through practical application, has received good effect.

Five, the specific embodiment

Tower machine is adjustable attachment device encloses square bearer structure by the back rest 1, two longerons 2 and front-axle beam 3, on device inner opposite angle line, there is raker beam 4, longeron 1 two ends are that bearing pin connects, strut in framework is removable, be divided into internal overarm support 8 and outer strut 9, during installation, one hangs in from standard knot the inside, and one hangs in from standard knot outside, then with 3 bolts, two struts firmly connected.Strut end is provided with adjusts bolt 14, and inside and outside

strut

8,9 holds out against on the limit of standard section main angle steel 10 by adjusting bolt 14.

There are clamping plate 5 at raker beam 4 two ends, and two ends clamping plate 5 are arranged on respectively on front-axle beam 3 and the back rest 1.Clamping plate 5 are isosceles triangle shape, by upper lower plate, by guide-localization piece 11 weld togethers, rear plate two base angles are fixed on the back rest 1 and longeron 2, and front plate two base angles are fixed on front-axle beam 3 and longeron 2, the drift angle of clamping plate 5 connects raker beam 4, and clamping plate 5 are connected by bearing pin I 13 with raker beam 4.In the interior guide positioning plate of clamping plate 5 11 outsides, wedge frame 6 is housed, wedge frame in two kinds of situation, is respectively used in standard section main angle steel sheet with rib and the situation of sheet with rib not.While there is no gusset in standard section main angle steel, wedge frame 6 is tip, and insert in the guide positioning plate 11 of clamping plate 5 one end of wedge frame 6, and wedge frame 6 other ends withstand on standard section main angle steel interior angle place; While having gusset in standard section main angle steel, use tack wedge frame 6 instead, wedge frame end head immediate roof is on gusset.Then, between guide-localization piece 11 and wedge frame 6, squeeze into wedge 12, to hold out against standard section main angle steel 10.At longeron 2 two ends, there is voussoir 7, squeeze into voussoir 7 and make Wai Mian Wedged of standard section main angle steel tight.Longeron 2 two ends are connected with spring cotter 16 by bearing pin II 15.The back rest 1 adopts the version of the channel-section steel side of spelling; Longeron 2 adopts the version of the channel-section steel side of spelling; Front-axle beam 3 adopts the version of the channel-section steel side of spelling; Clamping plate 5 are triangular-arc, are to form with Plate Welding, and there is respectively connecting bore at place, three angles, for connecting the raker beam at front and rear beam, longeron and diagonal line place.
