Abstract
The utility model discloses a jacking cross beam structure of a tower crane. The jacking cross beam structure consists of an upper cover plate, a lower cover plate and a middle web plate, wherein an ear plate seat is arranged in the middle of the upper cover plate, an ear plate with a lifting hole is fixed on the ear plate seat, ribbed plates connected with the lower cover plate are respectively fixed on two sides of the ear plate, two side ends of the web plate are respectively fixedly connected with a connecting square steel through a sealing plate, the connecting square steel is provided with a pin shaft; a bolt type locking device is horizontally arranged on the sealing plate; the bolt type locking device consists of a bolt seat and a bolt, wherein the bolt seat is fixedly arranged on the web plate, and the bolt is arranged between a pin hole of the bolt seat and a pin shaft hole in the sealing plate and can relatively move and perpendicularly extend out of the sealing plate so as to play a locking role. The jacking cross beam structure has the characteristics of being reasonable and compact in structure, convenient and reliable to use, good in safety and the like.
Description
Technical field
The utility model relates to a kind of jacking cross beam structure of tower machine, especially a kind of jacking cross beam structure for tower machine climbing support with blocking device.
Background technology
The jacking cross beam structure of existing tower machine climbing support, mainly by upper cover plate, lower cover and middle web, formed, centre at upper cover plate is provided with ear plate base, is fixed with the otic placode with lifting hole(eyelet) on it, and the both sides of described otic placode are fixed with respectively the lower gusset that connects lower cover; Described web two side ends is fixed with respectively a connection square steel with bearing pin; The jacking cross beam that said structure forms owing to there is no blocking device, easily produces coming off of jacking cross beam, once the serious accident that comes off and there will be tower machine to collapse in tower machine jacking process.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of rational in infrastructure, compact, easy to use, reliable, the jacking cross beam structure of the tower machine that safety is good.
The purpose of this utility model completes by following technical solution, the jacking cross beam structure of described tower machine, it is mainly comprised of upper cover plate, lower cover and middle web, centre at upper cover plate is provided with ear plate base, on it, be fixed with the otic placode with lifting hole(eyelet), the both sides of described otic placode are fixed with respectively the lower gusset that connects lower cover; Described web two side ends is fixed with a connection square steel with bearing pin by a shrouding respectively; On described shrouding, be horizontally installed with bolt-type latching device.
Described bolt-type latching device comprises: on web, be installed with a plug housing, be mounted with one and can relatively move and vertically stretch out outside shrouding and play the latch of locking effect between the pin-and-hole of described plug housing and pin shaft hole on shrouding.
On the web of described latch below, be provided with the round steel post of two evaginations, the spacing of two round steel posts is a bit larger tham the oblique curved latch handle portion external diameter arranging vertically downward that is on latch, and making latch stretch out shrouding and when locked position, the shank of latch handle is just between two round steel posts and block.
The utlity model has rational in infrastructure, compact, easy to use, reliable, the feature such as safety is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2, the jacking cross beam structure of tower machine described in the utility model, it is mainly comprised of upper cover plate 1, lower cover 2 and middle web 3, in the centre of upper cover plate 1, be provided with ear plate base 4, on it, be fixed with the otic placode 6 with lifting hole(eyelet) 5, the both sides of described otic placode 6 are fixed with respectively the lower gusset 7 that connects lower cover 2, and it can play the intensity of strengthening whole beam structure; Described web 3 two side ends are fixed with a connection square steel 10 with bearing pin 9 by a shrouding 8 respectively; On described shrouding 8, be horizontally installed with bolt-type latching device.
Bolt-type latching device shown in figure, it comprises: on web 3, be installed with a plug housing 11, be mounted with one and can relatively move and vertically stretch out outside shrouding 8 and play the latch 12 of locking effect between the pin-and-hole of described plug housing 11 and pin shaft hole on shrouding 8.
On the web 3 of described latch 12 belows, be provided with the round steel post 13 of two evaginations, the spacing of two round steel posts 13 is a bit larger tham oblique curved latch handle portion 14 external diameters that arrange vertically downward that are on latch 12, and making latch 12 stretch out shrouding and when locked position, latch handle portion 14 is just between two round steel posts 13 and block.
