To achieve these goals, this utility model provides a kind of tower crane device, comprising: pedestal; The electric pushrod support is installed in the lower surface of pedestal; Electric pushrod, its upper end are arranged on the electric pushrod support; Supporting plate, its upper surface is connected with the bottom of electric pushrod; This tower crane device also comprises booster parts, and the upper end of booster parts is connected on the electric pushrod support, and the bottom of booster parts is connected the upper surface of supporting plate.
Further, booster parts and electric pushrod be arranged in parallel.
Further, the electric pushrod support comprises: upper backup pad, lower supporting plate and be arranged on upper backup pad and lower supporting plate between joint pin, the motor of electric pushrod is arranged in the motor space between upper backup pad and the lower supporting plate, the execution bar of electric pushrod passes lower supporting plate and extends downwards, and the upper end of booster parts is connected the lower surface of lower supporting plate.
Further, the quantity of booster parts is two, is arranged side by side the both sides at the execution bar of electric pushrod.
Further, between pedestal and electric pushrod support, be provided with intermediate bar.
Further, between the upper surface of the bottom of electric pushrod and booster parts and supporting plate, be provided with extension bar.
Further, the motor of electric pushrod is connected the lower surface of upper backup pad by bolt, and booster parts is connected the lower surface of lower supporting plate by bolt.
Further, booster parts is pneumatic spring or cylinder.
According to tower crane device of the present utility model, at splint upper surface booster parts is set, auxiliary electric pushrod carrying load has transporting velocity faster when making the tower crane device can bear than heavy load, has improved the work efficiency of tower crane.
Description of drawings
The Figure of description that constitutes the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used to explain this utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of an embodiment of this utility model tower crane device; And
Fig. 2 is the structural representation of another embodiment of this utility model tower crane device.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
According to embodiment of the present utility model, a kind of tower crane device is provided, as shown in Figure 1, comprise: pedestal 10, lower surface at pedestal 10 is equipped with electric pushrod support 30, and electric pushrod support 30 comprises upper backup pad 31, lower supporting plate 32 and the joint pin 33 that connects upper backup pad 31 and lower supporting plate 32; The motor of electric pushrod 40 is arranged on the lower surface of upper backup pad 31 by bolt, and its bottom is connected by bolt equally with the upper surface of supporting plate 50; In addition, this tower crane device also comprises booster parts 60, and its upper end is connected the lower surface of lower supporting plate 32 by bolt, and its bottom is connected the upper surface of supporting plate 50 by bolt.
Preferably, use two booster parts 60, be set in parallel in the both sides of the execution bar of electric pushrod 40, such disposing helps the stress balance of tower crane device in handling process, and better promotes load capacity and accelerate transporting velocity.
In addition, booster parts 60 can also adopt cylinder, when needs were carried load downwards, the piston rod that switches the airflow direction control cylinder by electromagnetic valve extended downwards, and auxiliary electric pushrod 40 promotes supporting plate 50 downwards, realize load transportation downwards apace, during backhaul,, the piston rod of cylinder is upwards bounced back by the airintake direction of switching solenoid valve change cylinder, auxiliary electric pushrod 40 is fast lifting upwards, has reached the purpose of accelerating transporting velocity, improving load capacity equally.
Because electric pushrod 40 all is to adopt bolt to be connected with booster parts 60, can pull down from the tower crane device, therefore can select suitable electric pushrod 40 and booster parts 60 to be installed on the tower crane device according to the situation of load and use, to satisfy the different demands of different user to the tower crane load capacity.
In order to adapt to different carrying strokes, the tower crane device of this utility model embodiment also has been equipped with intermediate bar 20 and extension bar 70, intermediate bar 20 is installed between pedestal 10 and the electric pushrod support, and extension bar 70 is installed between the upper surface of the bottom of electric pushrod 40 and booster parts 60 and supporting plate 50.Concrete use, can according to practical situation select intermediate bar 20 or extension bar 70 one of them, for example shown in Figure 1, only use extension bar 70, also can in the tower crane device, use intermediate bar 20 and extension bar 70 simultaneously as shown in Figure 2.The use that is arranged so that the tower crane device like this is more flexible, helps the tower crane device and uses in wider scope.
