Abstract
The utility model relates to a hydraulic support device of an internal climbing crane, which comprises two climbing beams, and is characterized in that each climbing beam is equipped with two hydraulic jacks, while the four hydraulic jacks on the two climbing beams are distributed on a vertical projected line at a tower placing leg, the hydraulic jacks are fixedly connected to the climbing beams via supports provided with baffle plates, and the hydraulic jacks are arranged at the inner side of the baffle plates. The hydraulic support device of the internal climbing crane has the advantages that the force on the placing leg of the crane body can be adjusted uniformly when the internal climbing crane climbs on the climbing beams to guarantee crane verticality.
Description
Technical field
The utility model relates to a kind of hydraulic supporting device, particularly a kind of inside-climbing tower crane hydraulic supporting device.
Background technology
When building high-rise building, because it highly substantially exceeds the height that existing tower crane can reach, therefore adopted a kind of tower crane that can be installed on the side of buildings bearing support at present, rising along with the building height of building, hydraulic jacking system on the base section of tower crane dependence tower crane bottom is finished along building and is climbed, in the construction of reality, the installation of inside-climbing tower crane and climbing puts in place shelves four of all requiring the supporting tower crane and shelves a little on same horizontal surface, makes the stressed even as much as possible of each point.Otherwise the following beam that climbs stressed there is very big influence, if four of supporting tower crane shelve a unbalance stress, may cause inside-climbing tower crane dangerous situation when hoisting heavy, to occur, owing to often be difficult to accomplish four whole levels of turning over pin on framework, supporting-point, the body of the tower at the scene, be with certain degree of difficulty and risk to construction.Therefore demand inventing a kind of device that can solve the supporting discontinuity of inside-climbing tower crane urgently.
Summary of the invention
The purpose of this utility model is to solve inside-climbing tower crane to climb on the beam four to shelve the discrepancy in elevation is a little arranged, thereby makes four problems of shelving a discontinuity equalization of tower crane.A kind of inside-climbing tower crane hydraulic supporting device is provided.The utility model designs a kind of inside-climbing tower crane hydraulic supporting device, comprise two beams that climb, it is characterized in that: the every beam that climbs is provided with two hydraulic jacks, four hydraulic jacks on two beams that climb are distributed in body of the tower and shelve in the vertical projecting line of pin, hydraulic jack is fixedly connected on the beam that climbs by bearing, baffle plate is arranged on bearing, and hydraulic jack is positioned at the baffle plate inboard.The utility model has the advantages that can be at the inside-climbing tower crane Liang Shanghou that climbs that climbs to, regulate body of the tower shelve pin stressed evenly, guarantee the squareness of tower crane.
Description of drawings
Accompanying drawing 1 is the initial condition scheme drawing that climbs of the tower crane in the utility model,
Accompanying drawing 2 is the view that puts in place of climbing of the tower crane in the utility model,
Accompanying drawing 3 is returned to the initial condition scheme drawing for the tower crane in the utility model climbs,
Accompanying drawing 4 structural representations of the present utility model,
Accompanying drawing 5 is the running condition scheme drawing that is installed on the beam that climbs of the present utility model,
Below in conjunction with accompanying drawing and example the utility model is elaborated.
The specific embodiment
Tower crane 11 is positioned on the building 12 and prepares to climb among Fig. 1, and three road frameworks 13 are arranged on building 12, the beam (not marking among the figure) that wherein climbs on two frameworks below, the tower crane that the hydraulic efficiency pressure system on the base section under the tower crane can jacking top.Be located on the central frame 13 after tower crane 11 climbs among Fig. 2, finish once and climb.Comprise two beams 1 that climb among Fig. 3,4, it is characterized in that: every beam 1 that climbs is provided with climb four hydraulic jacks 2 on the beam 1 of 2, two of two hydraulic jacks and is distributed in body of the tower and shelves in the vertical projecting line of pin 4.Hydraulic jack 2 is fixedly connected on the beam 1 that climbs by bearing 5, and baffle plate 3 is arranged on bearing 5, and hydraulic jack 2 is positioned at baffle plate 3 inboards.
Four hydraulic jacks 2 corresponding to the beam 1 that climbs on the tower crane 11 have four bodies of the tower to shelve pin 4, when tower crane 11 is installed or climbed to when climbing beam 1, shelve pin 4 and can open on four hydraulic jacks 2 that set aside on the beam 1 that climbs for four on the tower crane 11, shelving of beam 1 a little has the discrepancy in elevation if at this moment climb, or the bottom surface Mismachining tolerance of shelving pin 4, the capital causes the body of the tower squareness not meet the demands, cause certain shelve pin 4 with shelve a little do not contact fully or four shelve a discontinuity, thereby have influence on the stressed of beam 1 and following structure that climb.It is to be shelved on four hydraulic jacks 2 that but present four bodies of the tower are shelved pin 4, can be earlier just calculate each shelve locate stressed, hydraulic jack 2 jack-up then, to tower crane shelve pin 4 apply each shelve a little should be stressed 30%～50%, can guarantee hydraulic jack 2 and shelve pin 4 and fully contact, again can jack-up tower crane 11.At this moment measure the squareness of tower crane 11, as long as by adjusting the top lifting height of four hydraulic jacks 2, just can make the squareness of tower crane 11 reach installation requirement, four of four hydraulic jack 2 places formation shelve a little stressed even substantially.Then the load of tower crane is transferred to fully the beam that climbs shelve a little on.
Because the deadweight and the lifted load of inside-climbing tower crane 11 are bigger, therefore adopt large-tonnage hydraulic jack 2, guaranteed the safety of practice of construction.Before inside-climbing tower crane 11 does not set aside on the beam that climbs as yet fully, the method of the both direction squareness by measuring body of the tower, guarantee that body of the tower is vertical, the suitable height of hydraulic jack 2 jack-up then, promptly defining identical supporting power acts on tower crane 11 and shelves on the pin 4, guarantee that support hydraulic jack 2 and body of the tower four shelve pin 4 and contact, avoided like this since on the beam that climbs four shelve the problem that load distribution that a discrepancy in elevation causes changes.
Claims (2)
1. an inside-climbing tower crane hydraulic supporting device comprises two beams that climb, and it is characterized in that: the every beam that climbs is provided with two hydraulic jacks, and four hydraulic jacks on two beams that climb are distributed in body of the tower and shelve in the vertical projecting line of pin.
2. by the described a kind of inside-climbing tower crane hydraulic supporting device of claim 1, it is characterized in that: hydraulic jack is fixedly connected on the beam that climbs by bearing, and baffle plate is arranged on bearing, and hydraulic jack is positioned at the baffle plate inboard.
