Abstract
The utility model discloses a movable base for a support leg of a tyre crane. The movable base comprises a main plate. The main plate is hinged with a movable wing plate which cannot be upturned, and the main plate is provided with a support leg tray matched with the support leg. When the movable base disclosed by the utility model needs to be used, the movable wing plate of the movable base is expanded on the ground, and the support leg of the crane is put in the support leg tray on the main plate, thus, the indirect ground contact area of the support leg of the crane is greatly increased, the pressure of the crane to the ground is correspondingly reduced, and the working range of the crane under a severe environment is broadened. When the movable base is not used at ordinary times, the movable wing plate of the movable base is retracted downwards, thus, the position occupied by the movable base is reduced, and the movable base can be conveniently stored and transferred. Compared with sleepers and base plates used in the past, the stability and the strength of the movable base disclosed by the utility model are greatly improved. Moreover, the movable base for the support leg of the tyre crane is convenient, fast, time-saving and labor-saving in use.
Description
[technical field]
The utility model relates to a kind of supporting leg base, is specifically related to a kind of mobile base of rubber tired crane supporting leg.
[background technology]
Rubber tired crane uses comparatively frequent in the project of transmitting and converting electricity construction, workyard environment in the work is generally more abominable, particularly in the situation that run into the operation ground such as rare soft, silt, hoisting crane supporting leg base produces owing to ground contact area is too small and sink, cause it can not normal operation, therefore must lay in its lower section the object enlarge active surfaces such as backing plate, make the hoisting crane quietly face that falls, and then satisfy lifting requirements.And lay and purchase at the scene time-consuming taking a lot of work of suitable backing plate, also may cause potential safety hazard, bring very large inconvenience to engineering construction.
[utility model content]
In view of this, for overcoming the deficiencies in the prior art, the utility model provides a kind of mobile base of rubber tired crane supporting leg.
The technical solution of the utility model is: a kind of mobile base of rubber tired crane supporting leg, described mobile base comprises mainboard, described mainboard be hingedly connected with can not on the movable wing plate that turns over, and be provided with the supporting leg pallet that matches with supporting leg at mainboard.
Preferably, be equipped with reinforced rib on the hinged limit of described mainboard and movable wing plate.
Preferably, described mainboard is square, and movable wing plate is semicircle, and reinforced rib is arranged on the edge of mainboard upper surface four edges and movable wing plate upper surface straight flange.
Preferably, described mainboard straight flange and the semi-round straight flange of movable wing plate are hinged by the steel hinge.
Preferably, described supporting leg pallet is annular pallet, and the annular distance size is identical with the cross section of hoisting crane supporting leg.
The mobile base of the rubber tired crane supporting leg that the utility model is designed, movable wing plate with mobile base when needs use launches on the ground, then the hoisting crane supporting leg is put in the annular brace leg pallet on the mainboard, the indirect earthed area of hoisting crane supporting leg is increased greatly, reduced accordingly the pressure of hoisting crane to ground.When not using at ordinary times, the movable wing plate of mobile base can be packed up downwards, just reduced the occupation of land position of mobile base, the depositing and being transported of portable propelling base.
The mobile base of the rubber tired crane supporting leg that the utility model provides, use the greatly enhancings such as simple and convenient, the sleeper of before use of stability and intensity, backing plate, increased the operating range under the hoisting crane harsh environment, improved operating efficiency, time saving and energy saving.

Fig. 1 is schematic top plan view of the present utility model.
Fig. 2 is that master of the present utility model looks schematic diagram.
Fig. 3 is work schematic diagram of the present utility model.
[specific embodiment]
For understanding better the utility model, below with reference to specific embodiment the utility model is described in detail.
See also Fig. 1, Fig. 2 and Fig. 3, the mobile base of the described a kind of rubber tired crane supporting leg of the present embodiment comprises a mainboard 1 that is formed by steel plate cutting, mainboard 1 be articulated and connected formed by the steel plate cutting four can not on the movable wing plate 2 that turns over.Usually the cross section of hoisting crane supporting leg is circular, therefore be welded with an annular arrangement supporting leg pallet 3 that is formed by the steel plate cutting equally in the middle of the described mainboard 1, and the annulus bore dia of annular arrangement supporting leg pallet 3 equals the diameter of hoisting crane supporting leg, annular arrangement supporting leg pallet 3 and hoisting crane supporting leg are stuck, in order to fixing supporting legs, prevent the slippage of supporting leg in the operation process.Described mainboard 1 is square, and movable wing plate 2 be semicircle, and has welded reinforced rib 4 at the edge of square four edges and semicircle straight flange and increase intensity, and excessive moment of flexure causes on the movable wing plate 2 and turns over when avoiding using.Mainboard 1 and movable wing plate 2 are hinged by the steel hinge 5 at corresponding square four straight flanges and four semicircle straight flange places, such linkwork can be when not using at ordinary times, four movable wing plates 2 is rotated down packs up, reduce to take up an area the position, the depositing and being turned round of portable propelling base.When needs use, with four wing plates 2 of the mobile base of rubber tired crane supporting leg at ground spreading, then the hoisting crane supporting leg is put in the annulus hole of annular arrangement supporting leg pallet 3, so just greatly increased the indirect earthed area of hoisting crane supporting leg, reduce accordingly the pressure of hoisting crane to ground, increased the operating range under the hoisting crane harsh environment.
The utility model can improve operating efficiency greatly, before having changed hoisting crane under harsh environment, manually lay railway sleepers during operation temporarily, the process of backing plate, use simple and conveniently, time saving and energy saving.
The above embodiment has only expressed a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
