Folding type support disk

Abstract

The invention belongs to support structures, in particular to a folding support plate. The folding support plate comprises a piston which is connected with a vehicle, two or more pull rod sliding bases are arranged on the side wall of the piston and can be slid up and down along the side wall of the piston, the pull rod sliding bases are hinged with pull rods, a base is arranged below the piston, a ball head of the piston is fixedly connected on the top surface of the base, slopes are arranged on the positions which are corresponding to the pull rods and arranged on the side wall of the base, lugs are arranged on the side wall below the slopes, folded plates are fixed on the lugs through rotary shafts and hinged with the pull rods through lower shafts, and the folded plates can be rotated by taking the rotary shafts as the shafts under the action of the pull rods. The folding support plate has the effects that: 1. the effective working area of the support plate can be increased through the folding mode, thereby allowing the vehicle to carry the larger support plate under the situation of not increasing the additional space, having no need of carrying a bulky stow wood and saving manpower and material resources; and 2. the support plate can realize the automatic one-time leveling of the ground slope by relying on the sliding bases.

Description

technical field [0001] The invention belongs to a support body structure, and particularly relates to a foldable support plate. Background technique [0002] The vehicle-mounted support plate is generally installed on a truck crane, a truck-mounted crane or a special vehicle. Its function is to fix the vehicle when the vehicle starts to work (including lifting, hoisting, etc.) to ensure the stability of the vehicle. The disadvantage of the existing support trays is that due to the limitation of vehicle space, the circular support trays with smaller diameters are installed. When the equipment is deployed in soft, riverine or semi-desert grounds, the small support trays cannot provide enough support. In order to prevent the equipment from sinking, the vehicle must also carry dunnage pads under the support plate to increase the contact area and reduce the specific pressure on the ground. The dunnage is large and heavy, and it is very inconvenient to carry it manually. SUMMARY...

Problems solved by technology

The disadvantage of the existing support plates is that due to the limitation of vehicle space, circular support plates with small diameters are installed. When the equipment is deployed on soft ground, river beach or semi-desert ground, the small support plates cannot provide sufficient support. The supporting area, in order to prevent the equipment from sinking, the vehicle must also carry a skid under the support plate to increase the contact area and reduce the specific pressure on the ground, and the skid is large and heavy, and it is very inconvenient to carry it manually
