Description
Technical Field
The invention relates to an excavator detection platform, in particular to an excavator traction force and excavating force detection platform.
Background
With the increasing competition of excavator products, the detection of the excavator products tends to be more and more refined, and the original extensive detection or no detection obviously cannot meet the design verification requirements of new generation products.
In the original traction force detection of the excavator, one excavator is adopted to pull the other excavator, the detection is carried out on an earth runway (GB/T6375-2008 soil works mechanical traction force testing method is required), and the excavator can not exert the maximum traction force because the friction coefficient of earth running to the road surface is small, the hardness of the road surface is low, the crawler belt is not fixed at all, the slipping phenomenon occurs frequently in the detection process, and the excavator can not exert the maximum traction force at all.
In the conventional excavator excavation force detection, the excavator is placed on a horizontal rigid non-stationary loading platform (the method for measuring the excavation force of the hydraulic excavator and the excavating loader is required by GB/T13332-2008). However, in the process of detecting the excavating force, the condition that the excavator translates together with the platform or the whole excavator slips often occurs, and the excavator has great potential safety hazards (the safety measures on GB/T13332-2008 are the machine installation tethering device and the stop block device so as to prevent slipping and tipping, and the excavator is poor in operability and very poor in safety guarantee in the actual use process). Meanwhile, the fixed point at the other end of the excavation force in the fixed state is inconvenient to adjust up and down and unstable, the measured state is not accurate, and data are inaccurate.
Disclosure of Invention
The invention aims to solve the technical problems of unstable detection data and low detection efficiency caused by skid of an excavator crawler, unstable anchor pile points and complicated adjustment in the existing detection of the traction force of the excavator, and provides an accurate, safe, stable and efficient detection platform for detecting the excavating force and the traction force of the excavator.
The technical scheme for achieving the purpose of the invention is as follows: the utility model provides an excavator testing platform, its characterized in that includes the ground anchor stake of inlaying in reinforced concrete ground, fixes the subaerial damping steel sheet of ground anchor stake side, the upper surface of damping steel sheet is provided with the rib that a plurality of mutual parallels and interval are arranged, the part that ground anchor stake exposes ground is provided with a plurality of bolt holes from bottom to top, the axial of bolt hole with rib on the damping steel sheet is parallel. In the invention, when the excavating force and the traction force of the excavator are tested, one end of the tension sensor is connected with the ground anchor pile through the flexible rope or the hanging strip, the other end of the tension sensor is connected with the excavator through the flexible rope or the hanging strip, the excavator is parked on the damping steel plate, the ribs on the damping steel plate and the crawler belt of the excavator generate enough resistance, the excavator can be prevented from skidding, the ground anchor pile can provide enough tension, and meanwhile, for the excavators with different tonnages, the traction force and the excavating force of the excavator can be accurately, safely, stably and efficiently detected by adjusting the tie points on the ground anchor pile.
In the excavator detection platform, the damping steel plates are arranged on two opposite sides of the ground anchor pile. Further, the positions of the damping steel plates at the two sides of the pit are higher than the bottom surface of the pit. The heights of the two damping steel plates are different. The number of the ground anchor piles in the pit can be two or more, and the plurality of ground anchor piles are arranged in parallel. Therefore, the excavating force of the excavator can be detected on one side of the damping steel plate, and the traction force can be detected on the other side of the damping steel plate, so that the efficiency and the use of the detection platform are improved, and different detection is convenient.
In the excavator detection platform, the ground of the damping steel plate is a concrete ground, and the bottom surface of the damping steel plate is welded with a plurality of steel columns fixedly connected in the concrete ground.
In the excavator detection platform, guardrails are arranged on the two sides of the damping steel plate, wherein the directions of the two sides of the damping steel plate are consistent with the directions of the ribs.
Compared with the prior art, the excavator excavating force and traction force detection platform is novel in structure, simple, effective and reasonable in arrangement, can realize centralized detection of excavating force and traction force, and solves the problem that the excavator cannot exert maximum excavating force and traction force due to skidding caused by insufficient friction force between the crawler belt of the excavator and the ground in the detection process; the potential safety hazard that the excavator and the loading platform move together in the detection process is eliminated; the problems of unstable detection data and low detection efficiency caused by unstable anchor pile points and complicated adjustment are solved; the requirements of the digger with different tonnages on different positions of the anchor point for the digging force and the traction force detection of the digger with different tonnages can be met by adjusting the digger tied at different positions of the porous ground anchor pile. The damping steel plate and the ground anchor pile (the structure is subjected to dangerous section stress analysis) are embedded in reinforced concrete, and the damping steel plate and the ground anchor pile are firm and reliable in the use process.
