The base is fixedly connected with the tail end of a telescopic arm of a telescopic arm type crane. The workbench is connected on the base in a hinged mode. The linear pushing device is arranged between the base and the workbench. The control device controls the linear pushing device over moving during variation of an angle of elevation of the telescopic arm so as to enable the workbench to remain horizontal. The workbench is provided with a rotatable turn table and a rotation driving device which drives the turn table to rotate. The utility model further discloses the telescopic arm type crane which is provided with the aerial work platform. A sliding wheel shaft is prolonged, the aerial work platform is mounted on the sliding wheel shaft, and when aerial work equipment is used, a hoisting function can be reserved, and switching is of no need. According to the aerial work platform and the telescopic arm type crane with the same, the turn table is arranged on the workbench, after the angle of the turn table is changed, staff can be enabled to obtain better aerial work positions, and the aerial work platform is suitable for an existing telescopic arm type crane.
Description
Technical field
The utility model relates to a kind of Telescopic crane and a kind of high-altitude operation platform that is arranged on Telescopic crane.
Background technology
Often need to use aerial platform when carrying out aloft work, by lifting arm, personnel are transported to setting.Existing aerial platform mostly is specialized equipment, need extra investment during use, and function singleness can only be carried out the lifting operation of personnel and a small amount of article.In order to reduce client's purchase cost, some manufacturer production have gone out to have the Telescopic crane of high-altitude operation platform function, install the bench board that can remain level at the end of telescopic boom, be used for personnel's aloft work, because the chassis weight of Telescopic crane is large, its reliable lifting weight also is better than general aerial platform, this improvement has increased the use function of Telescopic crane, also can remove the client from and additionally purchase aerial platform, have good result of use.But existing improvement just can give rise to the high-altitude with personnel and article, and the bench board that uses can not be adjusted, and sometimes personnel is delivered to suitable control position, has affected work efficiency.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of high-altitude operation platform, and the Telescopic crane of this high-altitude operation platform is installed, and its manned position can be rotated, and makes personnel better near the aloft work position.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of high-altitude operation platform, comprise the pedestal of captiveing joint with the end of the telescopic boom of Telescopic crane, be hinged on bench board on pedestal, be arranged on the straight pushing device between pedestal and bench board and control the straight pushing device action so that the control setup of bench board maintenance level is provided with rotating rotating table and drives the rotating driving device that rotating table rotates on bench board when the telescopic boom elevation angle changes.
As to restriction of the present utility model, described straight pushing device is oil cylinder or Electrohydraulic push rod.
As another kind of the present utility model is limited, described rotating driving device is that the rotation that is arranged between rotating table and bench board promotes oil cylinder.
A kind of Telescopic crane, its telescopic boom end is equipped with the described high-altitude operation platform of above-mentioned any one.
As restriction, the two ends of the sheave shaft that the telescopic boom end is installed all stretch out and protrude from the outer wall of telescopic boom, and the pedestal of described high-altitude operation platform is arranged on the outstanding position at sheave shaft two ends.
Owing to having adopted above-mentioned technical scheme, the utility model compared with prior art, obtained technological advance is: high-altitude operation platform provided by the utility model, by rotating table is set on bench board, after the angle that changes rotating table, can make the position of the better aloft work of staff; Straight pushing device adopts oil cylinder or Electrohydraulic push rod, and technology maturation is used reliably, is convenient to buying and implements, and can effectively reduce cost; Rotating driving device adopts rotation to promote oil cylinder, and thrust is large, implements fairly simple; Telescopic crane of the present utility model by extending sheave shaft, is arranged on high-altitude operation platform on sheave shaft, can keep hoisting function when using as aerial lift device, does not need to switch.The utility model is applicable on existing Telescopic crane.
The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.

The specific embodiment
Embodiment
As shown in Figure 1 to Figure 3, the present embodiment discloses a kind of high-altitude operation platform and the Telescopic crane of this high-altitude operation platform has been installed, and high-altitude operation platform is installed on the end of telescopic boom 7 of Telescopic crane.
the bottom of high-altitude operation platform is pedestal 1, pedestal 1 is used for being fixedly connected on the end of telescopic boom 7, it can be used for installing other parts simultaneously, for mounting base 1, two sheave shafts 4 first telescopic boom 7 ends being installed extend to its two ends, the two ends of sheave shaft 4 are the outer wall one end distance of outstanding telescopic boom 7 all, at this moment, pedestal 1 is arranged on the outstanding position at sheave shaft 4 two ends, such benefit is that the part that sheave shaft 4 is positioned in the middle of telescopic boom 7 still is former state, can continue in the middle of it and the pulley cooperation, thereby install in the situation of high-altitude operation platform and still can keep hoisting function.
Hinged bench board 2 on pedestal 1, a straight pushing device 3 is installed between pedestal 1 and bench board 2, this straight pushing device 3 is under the control of a control setup, according to the elevation angle of telescopic boom 7 when working, corresponding push work platform 2 rotations, no matter thereby guarantee telescopic boom 7 under what angle, bench board 2 total energy maintenance levels.This straight pushing device 3 can adopt the various mechanism such as oil cylinder or Electrohydraulic push rod, when adopting oil cylinder, can utilize the hydraulic efficiency pressure system of Telescopic crane as propulsion source, only need to get final product to its power supply when Electrohydraulic push rod.Control setup can adopt the common controllers such as PLC, in order to guarantee the horizontal device of bench board 2, can corresponding angular transducer be set on bench board 2 or on telescopic boom 7, measure the linear pushing mechanism 3 of the rear control of angle variation according to angular transducer and move, carry out angle compensation.
Be provided with a rotating table 8 on bench board 2, rotating table 8 can rotate under the support of the center shaft 9 that is positioned at bench board 2, thereby makes the staff can solve control position.Simultaneously, corresponding rotating driving device is set on bench board 2 drives rotating table 8, it is that the rotation that is arranged between rotating table 8 and bench board 2 promotes oil cylinder 5 that the present embodiment is selected rotating driving device.After rotating table 8 rotations are complete, by corresponding locking cylinder 6 is set on bench board 2, both locked, thereby can keep both to fix.
