Background

In the construction of highway engineering, the deflection detection is carried out on a structural layer according to the standard requirement. The Beckman beam method is a method suitable for measuring the elastic deflection value of the road surface during static loading or very slow speed loading, and can well reflect the overall strength of the road surface. For example, the deflection detection of a roadbed and a water stabilization layer of a road surface structure is carried out by using a 5.4-meter Beckman beam. The detection frequency is one point per 20 meters of each lane, and when the conditions exist, two benders can be used for simultaneously measuring the left and right two-line vehicle zones. In the process of transition of each current detection point, a Beckman beam is lifted manually to move, so that time and labor are wasted, and the efficiency is low.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments. It is to be understood that the following description is only for purposes of clearly illustrating the present invention and is not to be taken in a limiting sense.

Referring to fig. 1 and 2, a vehicle-mounted suspension device for a beckman beam deflectometer is composed of an electro-hydraulic loop bar 4, a jaw 5, a steel wire rope I6, a lifting winch 7 and the like. In this example, the deflection test was performed in conjunction with a beckmann beam deflectometer having a length of 5.4 meters. The device is provided with two groups of electro-hydraulic loop bars 4, each group of electro-hydraulic loop bars consists of 4 sections of loop bars with the length of 1 meter, the total elongation is 4 meters, and the total contracted length is 1.4 meters. Two sets of electro-hydraulic loop bars 4 are installed respectively in the bottom of the truck 1 both sides of deflection, are located the tire 2 rear, and with horizontal plane parallel arrangement for place the graceful roof beam of becker on ground after, the graceful roof beam of becker can aim at the gap between the truck rear wheel of deflection. The electro-hydraulic loop bar 4 is connected with a storage battery of the deflection vehicle 1, the storage battery supplies electric energy to drive the deflection vehicle to stretch, and the transverse movement of the Beckman beam 3 is realized through stretching. A lifting winch 7 is arranged below the end part of each sleeve rod, and an electric lifting winch is adopted in the embodiment and connected with a storage battery of the deflection car 1 to supply power to the deflection car by taking the storage battery as a power supply. Each lifting winch 7 is wound with a steel wire rope I6, the lower end of each steel wire rope I6 is connected with a hook type clamping jaw 5, and the clamping jaw 5 is matched with a hole in the Beckman beam 3 and hung on the hole so as to be driven by the lifting winch 7 to lift the Beckman beam 3 in the vertical direction together with the steel wire rope I6.

The working process of the utility model is as follows:

after the detection personnel and instruments reach the detection section, the electro-hydraulic loop bar 4 arranged at the bottom of the deflection vehicle 1 is opened, the 4 sections of bars are all extended out, and the steel wire rope II 8 arranged above the end part of the outermost section of bar is hung at the top of the rear box of the deflection vehicle, so that the overhanging end of the electro-hydraulic loop bar 4 is prevented from being bent downwards, wherein the steel wire rope II 8 is driven by a lifting winch arranged above the end part of the outermost section of bar. And opening a lifting winch 7 below the end part of each section of rod to drop the steel wire rope I6 and the clamping jaw 5. The claw 5 is hung on the Beckman beam 3, and the lifting winch 7 is controlled to lift the Beckman beam 3 by 5-8cm, so that the Beckman beam is separated from the ground. The first section of the electric hydraulic sleeve rod 4 (namely, one end close to the deflection vehicle) is controlled to contract, and the Beckman beam 3 is driven to move towards the tire part of the deflection vehicle 1. And when the front end of the Beckman beam reaches the detection position, controlling the lifting winch 7 to lower the Beckman 3, and removing the lifting claw 5 to perform deflection detection. After the detection is finished, the electro-hydraulic loop bar 4 extends completely, the Beckman beam 3 is hung on the clamping jaw 5, the lifting winch 7 is controlled to lift the steel wire rope I6 upwards completely, and the Beckman beam is lifted until the electro-hydraulic loop bar 4 is in close contact with the Beckman beam, as shown in fig. 2. And starting the deflection vehicle to run to the next detection point. The above procedure was repeated for detection.

Through adopting the utility model discloses, improved deflection detection efficiency, reduced the testing personnel and dropped into, reduced the detection cost.

The above description is only the preferred embodiment of the present invention. Various modifications and equivalent changes may be made by those skilled in the art without departing from the spirit and scope of the present invention, and such modifications and changes are intended to be included within the scope of the present invention.
