Problems solved by technology

The existing railway wagon weight detection equipment, one is the track scale installed on the railway line, the disadvantage is that the wagon must leave the loading site to the track scale line for dynamic weighing at the required speed, and the overload and underload detected by the track scale , The unbalanced load problem is more troublesome to deal with, which seriously affects the efficiency of railway transportation and the economic benefits of cargo owners
Another type of on-site testing equipment is the wheel weight detector, which is heavy for manual handling and measurement. The 8 wheels of each carriage need to be measured separately, and then the weight of the 8 wheels is added up, and the weight of a single wheel is weighed. Affected by other wheels, the error is relatively large, and the vehicle number data is manually recorded, which is prone to errors. The whole process is labor-intensive and low-efficiency. If you weigh the entire truck, the labor intensity can be imagined, and some high-platform loading yards Difficult to carry out weighing operations in narrow gaps

Embodiment 1

[0036] see figure 1 , figure 2 , the present embodiment discloses a static weighing detection method for a railway vehicle, and its implementation is as follows:

[0037] 1) Use one or two self-propelled trolleys to run on the sleeper in the middle of the railway track under the vehicle;

[0038] 2) The self-propelled trolley is equipped with a lifting component and a load cell component; the vehicle is lifted by the lifting component, and two or four of the front bogie and the rear bogie are simultaneously lifted by one self-propelling trolley. two or four wheels of the bogie and weigh them; or if figure 1 As shown, one automatic walking trolley is used to lift two or four wheels of the front and rear bogies in turn and weigh them, or two front and rear automatic walking trolleys are used, and the front and rear two automatic walking trolleys Lift the two or four wheels of the front and rear bogies respectively and weigh them to obtain the vehicle quality signal;

[0039...

Embodiment 2

[0043] see figure 2 , image 3 , Figure 4 , the present embodiment discloses a self-propelled trolley for realizing the aforementioned railway vehicle static weighing detection method, such as figure 2 As shown: the self-propelled trolley includes a frame and a traveling mechanism, an electrical control system, and a hydraulic control system. Such as image 3 , Figure 4 As shown: there are two sets of lifting assemblies at the front and rear on the vehicle frame, and each set of lifting assemblies 4-2 includes two sets of left and right lifting mechanisms. 11 is fixed on the vehicle frame, and each group of lifting mechanisms is provided with at least one lifting cylinder 5, and each group of lifting mechanisms corresponds to a wheel of the train bogie; the hydraulic control system cooperates with the lifting components.

Embodiment 3

[0045] The difference between the self-propelled trolley disclosed in this embodiment and used to implement the above-mentioned static weighing detection method for railway vehicles is that a group of lifting components are provided on the frame, and the left and right two parts are used for weight measurement. The group lifting mechanism lifts a wheel on both sides of the front or rear of the train bogie respectively.

Abstract

The invention relates to an automatic walking trolley and a railway vehicle static load detecting system. According to the automatic walking trolley, lifting components are arranged on a trolley frame of the trolley. Each lifting component group comprises a left lifting mechanism group and a right lifting mechanism group. Each lifting mechanism group corresponds to a wheel of a train steering frame. The railway vehicle static automatic detecting weighing system comprises the automatic walking trolley and a control processing system. A weighing sensor is arranged on the automatic walking trolley. Output signals of the weighing sensor are connected into an electric appliance control system of the automatic walking trolley which is connected with a control processing system through a wireless communication module. According to a railway vehicle static weighing detecting method, the automatic walking trolley runs on a sleeper in the middle of a railway track below a vehicle, the vehicle is lifted up through the lifting components and is weighed, vehicle weight signals are obtained, then the received vehicle weight signals are subjected to operation processing through the control processing system, and vehicle load and unbalance load data are obtained.

Description

technical field [0001] The invention relates to a railway vehicle load detection method and system, in particular to a railway vehicle static weighing detection method, a railway vehicle static automatic detection and weighing system and an automatic walking trolley. Background technique [0002] With the rapid development of our country's economy, the transportation of goods is becoming more and more frequent, and railway freight has become the mainstream, so railway safety is particularly important. The existing railway wagon weight detection equipment, one is the track scale installed on the railway line, the disadvantage is that the wagon must leave the loading site to the track scale line for dynamic weighing at the required speed, and the overload and underload detected by the track scale , The unbalanced load problem is more troublesome to deal with, which seriously affects the efficiency of railway transportation and the economic benefits of cargo owners. Another ty...
