Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
As shown in fig. 1 and 2, the automatic safety protection device for jacking of the tower crane comprises a tower crane foundation bearing platform body 1, an anti-toppling protection mechanism 2 and a ground fixing plate 3; the anti-toppling protection mechanism 2 comprises a side sleeve 21, a telescopic cylinder 22 and a proximity switch 23, wherein the side sleeve 21 is sleeved on the outer side of the tower crane foundation bearing platform body 1; one end of a telescopic cylinder 22 is fixed at the bottom of the side extension sleeve 21, and the telescopic end of the telescopic cylinder 22 is arranged in a direction vertical to the ground fixing plate 3; the proximity switch 23 is arranged at the bottom of the side extension sleeve 21, the detection end of the proximity switch 23 is arranged right opposite to the ground, and the proximity switch 23 is electrically connected with the telescopic cylinder 22 through a control circuit; the tower crane foundation bearing platform body 1 is fixedly connected with the ground fixing plate 3 through the supporting legs 4. The ground fixing plate 3 is fixedly connected with the ground, so that the surface of the ground fixing plate 3 connected with the ground is large, and the connection is stable enough.
The utility model discloses an application principle lies in, through the protection machanism 2 that prevents empting that sets up in the tower crane foundation cushion cap body 1 outside, the supporting legs 4 that prevent 1 bottom of tower crane foundation cushion cap body are bearing and are not living tower crane top structure weight and lead to whole tower crane slope, so that when toppling over to one side, proximity switch 23 of installation is received with 3 distance production changes on the side cover 21 in the tower crane foundation cushion cap body 1 outside preferentially, trigger the telescopic cylinder 22's of being connected with proximity switch 23 control circuit UNICOM, telescopic cylinder 22 stretches out and draws back fast and realizes that the tower crane foundation cushion cap body 1 outside supports the increase that leans on the fulcrum with ground, improve and support the reinforce, prevent further toppling over of tower crane foundation cushion cap body 1 and turn on one's side.
The bottom that telescopic cylinder 22 is close to ground one side is equipped with adsorption disc 5, and adsorption disc 5 opening is down, upper end and telescopic cylinder 22 fixed connection. Adsorption disc 5 plays telescopic cylinder 22 and topples over in tower crane foundation cushion cap body 1 side direction and lean on when leaning on, gives certain effort and reaction force buffering effect, still plays the effect of certain absorption ground fixed plate 3.
The shape of the inner side of the side sleeve 21 is matched with the shape of the tower crane foundation bearing platform body 1, and the outer side of the side sleeve 21 is a cylinder; the outer side of the side extension sleeve 21 is laterally driven into the tower crane foundation bearing platform body 1 through a bolt 6 and is connected with the tower crane foundation bearing platform body 1 through a detachable bolt 6. Side fixed mode that inclines cover 21 and the tower crane foundation cushion cap body 1 outside, it is certain to ensure proximity switch 23 and ground fixed plate 3's distance, when tower crane foundation cushion cap body 1 topples to arbitrary one side, at first can lead to the proximity switch 23 and the ground distance of this side to change, proximity switch 23 is apart from the settlement of variation size by the initial setting of particular case, generally use 1 centimetre to change as the standard, exceed the change of one centimetre, consider that the tower crane of tower crane foundation cushion cap body 1 top has the risk of toppling over, trigger the control circuit between proximity switch 23 UNICOM and the telescopic cylinder 22, and trigger telescopic cylinder 22 and stretch out and draw back fast and lean on ground, provide the holding power for the tower crane foundation cushion cap body 1 outside, prevent the risk that tower crane foundation cushion cap body 1 continues to topple over.
As shown in fig. 3, 3 telescopic cylinders 22 and 3 proximity switches 23 are fixed to the bottom of the side sleeve 21 in an embedded manner. 3 telescopic cylinder 22 have guaranteed that the telescopic cylinder 22 of side extension cover 21 bottom extends the back steadiness completely, prevent that one side from toppling over the risk that the reaction force that receives telescopic cylinder 22 leads to toppling over towards the other side after the trend takes place. 3 proximity switch 23's setting can supply to control a telescopic cylinder 22's flexible respectively, and the risk of empting of three face is monitored simultaneously, also can realize the change that one side took place the distance through a proximity switch 23 three telescopic cylinder 22's the mode of setting up of establishing ties, and the telescopic cylinder 22 of multiaspect stretches out the trend that further emptys of support side cover 21 and tower crane foundation cushion cap body 1 simultaneously.
As shown in fig. 4, the bottom of the side extension sleeve 21 is fixed with 4 telescopic cylinders 22 and 4 proximity switches 23 in an embedded manner, and one telescopic cylinder 22 and one proximity switch 23 are installed on one side of the tower crane foundation bearing platform body 1 in a matching manner. The same setting form is adopted, when the proximity switch 23 on one side detects that the distance changes, the telescopic cylinder 22 on the same side is controlled to quickly react and support, and the other three sides are synchronously stretched. Four proximity switches 23 can be connected in parallel through a controller, and when the change of the distance of one proximity switch 23 is detected, the controller controls the four proximity switches 23 to trigger and switch on a control circuit of the telescopic cylinder 22 at the same time, and controls the four telescopic cylinders 22 to stretch and retract at the same time.
The ground fixing plate 3 is fixedly connected with the ground, and the ground fixing plate 3 is made of metal. The ground fixing plate 3 made of metal is matched with the proximity switch 23 to serve as a function of the iron trigger, and when the passive proximity switch 23 is close to the ground fixing plate 3/iron trigger, the switch is controlled to be closed under the action of magnetic force inside the switch. The passive proximity switch 23 is ensured to be used without a power supply, and is non-contact, maintenance-free and environment-friendly.
Compared with the prior art, the utility model, following beneficial effect has:
the anti-toppling protection mechanism 2 ensures that if the tower crane foundation bearing platform body 1 finds a risk of inclining to any one side in the jacking process of the tower crane, a new supporting part can be provided in time, and the side sleeve 21 and the tower crane foundation bearing platform body 1 are supported; prevent that tower crane foundation cushion cap body 1 further topples over the risk and produces.
