Embodiment Construction

[0110] The above and other technical features and advantages of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0111] see figure 2 As shown, a lifting force measurement device 100 of the present invention includes a bracket 110 , a transverse shaft 120 , a pullback mechanism 130 , a flexible lifting mechanism 140 and a tension sensor 180 . The horizontal shaft 120 is disposed on the upper part of the bracket 110 .

[0112] Please combine image 3 As shown, the two ends of the pullback mechanism 130 are respectively a fixed end and a movable end. The fixed end is axially connected to the support 110 , and the movable end is connected to one end of the flexible lifting mechanism 140 . The flexible lifting mechanism 140 is wound around the transverse axis 120, and the other end of the flexible ...

Abstract

The invention provides a lifting force measuring device and equipment and method for measuring the actual locking rail temperature of a jointless track. The lifting force measuring device comprises a bracket, a transverse shaft, a back-pulling mechanism, a flexible lifting mechanism and a tension sensor. The fixed end of the back-pulling mechanism is in shaft connection with the bracket, and the movable end of the back-pulling mechanism is connected with one end of the flexible lifting mechanism; the transverse shaft is arranged on the upper portion of the bracket, the flexible lifting mechanism is wound around the transverse shaft, and the other end of the flexible lifting mechanism is provided with a clamp; the back-pulling mechanism pulls the flexible lifting mechanism to slide on the transverse shaft and drives a jointless track rail to move upwards; the tension sensor is arranged at the upper end of the clamp. By the adoption of the method, according to the equipment, the actual locking rail temperature of the jointless track can be obtained by measuring rail lifting force, rail lifting displacement and rail temperature, wherein the rail lifting force is measured by the lifting measuring device, the lifting displacement is measured by a displacement sensor, the rail temperature is measured by a temperature sensor. Accordingly, the actual locking rail temperature of the jointless track can be accurately measured.

Description

technical field [0001] The invention relates to the technical field of seamless railway lines, in particular to a lifting force measuring device, a measuring device and a method for actually locking rail temperature of seamless lines. Background technique [0002] At present, the total operating mileage of railways in my country is about 120,000 kilometers, and the mileage of seamless lines accounts for about 70%. The seamless line locking rail temperature is divided into the following four concepts, and their meanings are different, namely [0003] Nominal locking rail temperature: that is, the zero stress rail temperature, the rail temperature when the long rail in the freely expandable state is fastened to the sleeper with fasteners to lock it; [0004] Design locked rail temperature: that is, the neutral rail temperature, which is determined through the calculation of rail stability and strength according to the specific conditions of the line. For the convenience of c...
