Description

Technical Field

[0001] The utility model belongs to the technical field of rail detection equipment, and specifically relates to a hand-push type rail waist double-side temperature measuring device. Background Art

[0002] In a high or low temperature environment, the rails will exchange heat with the outside world, thereby changing the performance of the rails. When the rail wheels of the train are rolling on the track, the rail parts with higher or lower temperatures, or the rail parts with large temperature differences, are frequently stressed, resulting in performance degradation or cracks. Therefore, it is necessary to detect the rail temperature of the rails. There are two existing detection methods. The first is to contact the rail waist of the rail through a temperature sensor and detect the temperature of the rail. This method has low measurement efficiency; the second is to perform non-contact measurement of the rail waist through an infrared temperature sensor. This method has a large measurement deviation. The existing rail temperature measurement is mainly the temperature of the rail in a high temperature environment. Since the main heat of the rail comes from sunlight, and since sunlight cannot shine on both sides of the rail waist at the same time, the temperature on both sides of the rail waist cannot be consistent. The existing detection only measures one side of the rail waist, and thus cannot ensure that the detected temperature is the true value. Utility Model Content

DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] The utility model discloses a hand-push type rail waist 601 double-side temperature measuring device, such as Figure 1-7As shown, it includes an adjustable hand push frame 100, a mounting seat 200, a rear rolling type walking mechanism 300 and a front clamping type walking mechanism 400. Among them, the adjustable hand push frame 100 and the mounting seat 200 are detachably connected together, the rear rolling type walking mechanism 300 and the front clamping type walking mechanism 400 are installed at both ends of the mounting seat 200 at intervals along the pushing direction, the rear rolling type walking mechanism 300 rolls on the upper end surface of the rail top 603 of the rail 600, and the front clamping type walking mechanism 400 clamps and rolls on both sides of the rail top 603. The utility model is equipped with a plurality of plastic rail temperature detection mechanisms 500 on both sides of the mounting seat 200, and the end of each plastic rail temperature detection mechanism 500 faces the rail waist 601 of the rail 600. The working principle and advantages of the utility model are as follows: the steel rail 600 of the utility model comprises a rail bottom 602, a rail waist 601 and a rail top 603 from bottom to top, which form an I-shaped structure. When the temperature of the rail waist 601 of the steel rail 600 is detected, the front clamping walking mechanism 400 is clamped on both sides of the rail top 603, and the rear rolling walking mechanism 300 is arranged on the upper end of the rail top 603. Then, the adjustable hand push frame 100 is adjusted so that the inspector is located on one side of the steel rail 600 and holds the adjustable hand push frame 100 with both hands in a comfortable posture, and then each plastic form rail is pressed. The temperature detection mechanism 500 is bent and shaped so that the detection end of the plastic rail temperature detection mechanism 500 faces the rail waist 601, and then the detection personnel push the adjustable hand push frame 100 to move along the extension direction of the rail 600, so that the adjustable hand push frame 100 drives the multiple plastic rail temperature detection mechanisms 500 located on both sides of the rail waist 601 to move synchronously through the mounting seat 200, thereby achieving the purpose of synchronous temperature measurement on both sides of the rail waist 601, and taking the average value of the temperatures measured by the multiple plastic rail temperature detection mechanisms 500 on each side of the rail waist 601 to improve the detection accuracy. The rear rolling walking mechanism 300 and the front clamping walking mechanism 400 of the utility model can limit the mounting seat 200 on the rail 600, avoiding the lateral deflection of the mounting seat 200 on the rail 600 during the temperature measurement process, preventing large deviations in the temperature measurement data, and avoiding damage to other components due to hard contact with the rail 600 or the roadbed. The utility model can continuously measure the temperature of the rail 600 by pushing, and then the temperature change of the adjacent parts of the rail 600 can be obtained, and the corresponding parts of the rail 600 can be targetedly cooled by the detected data. In summary, the utility model can detect the temperature of both sides of the rail waist 601 at the same time, ensure the accuracy of the detection, and improve the efficiency of the detection, and can effectively reduce the difficulty of the detection operation and improve the convenience of detection and carrying.

[0028] As a preferred embodiment of the present invention, Figure 2As shown, the adjustable hand push frame 100 includes a mounting column 101 and two hand push rods 103. A connecting flange 102 is constructed at the lower end of the mounting column 101, and the connecting flange 102 is detachably connected to the upper end of the mounting seat 200. The two hand push rods 103 are both fixed on the mounting column 101 at one end close to each other, and the two hand push rods 103 are gradually opened outward from the mounting column 101. The hand push rod 103 of this embodiment includes a rod body in a bent shape, and a mounting sleeve 104 is constructed at the lower end of the rod body. The mounting sleeve 104 is mounted on the mounting column 101, and a threaded hole 105 is opened on the outer peripheral wall of the mounting sleeve 104. A locking bolt 106 is threadedly connected in the threaded hole 105, and the end of the locking bolt 106 abuts against the outer peripheral wall of the mounting column 101. A hand handle 107 is constructed at the upper end of the rod body. The working principle and advantages of this embodiment are as follows: before conducting rail temperature detection, the two locking bolts 106 are loosened, and then the two push rods 103 are rotated a certain angle along the axis of the assembly column 101, so that the two push rods 103 are offset to the outside of the rail 600 at one end away from the assembly column 101, and the opening and closing degrees of the two push rods 103 are adjusted to improve the hand-holding comfort of the operators, and the connection height of the two push rods 103 and the assembly column 101 are adjusted. After the adjustment is completed, the two locking bolts 106 are tightened to lock the relative positions of the two push rods 103 and the assembly column 101. Then, the operators hold the two hand handles 107 and push the entire device forward along the extension direction of the rail 600, thereby realizing continuous temperature measurement of the rail 600.

[0029] As a preferred implementation of the utility model, Figure 4 As shown, the mounting seat 200 includes a seat body 201, and two first connecting ears 202 are configured at one end of the seat body 201 away from the front clamping walking mechanism 400, and a connecting seat 203 is configured at the lower end of each first connecting ear 202. The rear rolling walking mechanism 300 of this embodiment includes a rolling wheel 301, and connecting shafts 302 are respectively configured at both axial ends of the rolling wheel 301, and the axis of each connecting shaft 302 coincides with the axis of the rolling wheel 301, and the connecting shaft 302 is rotatably connected with the corresponding connecting seat 203, and the rolling wheel 301 rolls on the upper end surface of the rail top 603, so that the rolling wheel 301 becomes the rear support structure of the device, and in the process of pushing the adjustable hand push frame 100 to walk, the rolling wheel 301 rolls on the rail top 603, so that the entire device moves smoothly on the rail 600. In this embodiment, limiting edges 303 are respectively constructed at both axial ends of the rolling wheel 301, each limiting edge 303 extends radially outward along the rolling wheel 301, and the rail top 603 is located between the two limiting edges 303, so that the rail top 603 is restricted between the two limiting edges 303, thereby preventing the rolling wheel 301 from deviating from the rail 600 during movement.

[0030] As a preferred embodiment of the present invention, Figure 4-6As shown, two second connecting ears 204 are constructed at one end of the seat body 201 away from the rear rolling walking mechanism 300, and a mounting hole 205 is opened on each second connecting ear 204. The front clamping walking mechanism 400 of this embodiment includes two first vertical shafts 401, and a bearing 402 is installed on the upper part of each first vertical shaft 401. The bearing 402 is installed in the corresponding mounting hole 205, thereby achieving the purpose of rotatably connecting the first vertical shaft 401 and the second connecting ear 204. A swing arm 403 is fixedly connected to the lower end of each first vertical shaft 401, and a second vertical shaft 404 is fixedly connected to the end of the swing arm 403 away from the first vertical shaft 401. A lateral wheel 405 is rotatably installed on the second vertical shaft 404, and an adjustable elastic telescopic component 407 is connected between the two second vertical shafts 404. Each lateral wheel 405 elastically rolls on the corresponding side of the rail top 603. The front clamping walking mechanism 400 of this embodiment serves as the front support structure of the entire device, and can effectively prevent the front end of the entire device from tilting upward or drooping downward. If the front clamping walking mechanism 400 adopts the same structure as the rear rolling walking mechanism 300, the operator needs to straighten the entire device at all times during the pushing process. If the operator contacts the external force that straightens the entire device, the entire device often tilts or overturns. The front clamping walking mechanism 400 used in this embodiment can effectively avoid the occurrence of the above situation, so that the entire device can stably walk on the rail 600 during the pushing process. After completing the temperature measurement operation, the embodiment can release the elastic connection of the adjustable elastic telescopic component 407 to the two second vertical shafts 404, and then each swing arm 403 is rotated along the axis of the first vertical shaft 401, so that the lateral wheel 405 is stored to the corresponding side of the mounting seat 200. The adjustable elastic telescopic component 407 of this embodiment includes two connecting springs 4071 arranged opposite to each other, and one end of each connecting spring 4071 is constructed with a connecting ring 4072, and the connecting ring 4072 is movably mounted on the upper end of the second vertical axis 404, and the other end of the connecting spring 4071 is constructed with an internal threaded sleeve 4073, and the two ends of the adjusting rod 4074 are respectively threadedly connected to the two internal threaded sleeves 4073. When the two lateral wheels 405 clamp the rail top 603 therebetween, the two internal threaded sleeves 4073 are brought closer to each other by rotating the adjusting rod 4074, thereby causing the two connecting springs 4071 to be elastically stretched to a predetermined degree. At this time, the two lateral wheels 405 are elastically pressed against the two sides of the rail top 603, and the elastic pressing force of the lateral wheels 405 on the side walls of the rail top 603 can be adjusted by adjusting the distance between the two internal threaded sleeves 4073. Under the premise of not affecting the rolling movement of the lateral wheels 405, the two lateral wheels 405 are prevented from twisting significantly under the action of lateral external force.In order to prevent the lateral wheels 405 from vertically deflecting during rolling on the side walls of the rail top 603, the present embodiment adopts the following measures: limiting edges 406 are respectively constructed at both axial ends of each lateral wheel 405, each limiting edge 406 extends radially outwardly of the lateral wheel 405, and the side edge of the rail top 603 is located between the two limiting edges 406, which serve to limit the vertical displacement of the lateral wheels 405.

[0031] As a preferred embodiment of the present invention, Figure 4 , 7 As shown, connecting plates 206 are respectively constructed on both sides of the mounting seat 200, and a plurality of assembly holes 207 are spaced apart on each connecting plate 206 along the extension direction of the steel rail 600, and each plastic rail temperature detection mechanism 500 is detachably connected to the connecting plate 206 through the assembly holes 207. The plastic rail temperature detection mechanism 500 of this embodiment includes a connecting tube 501, a shaping metal tube 502 and an infrared temperature sensor 503. Among them, the upper end of the shaping metal tube 502 is fixedly connected to the lower end of the connecting tube 501, and the infrared temperature sensor 503 is installed at the lower end of the shaping metal tube 502, and an external force can be applied to the shaping metal tube 502 to bend and shape it, so that the infrared temperature sensor 503 faces the corresponding position of the rail waist 601 of the steel rail 600, thereby realizing the measurement of the temperature of the rail waist 601 at a predetermined position, and the shaping metal tube 502 can be shaped at any time according to needs to change the angle and height of temperature measurement. The wire 504 connected to the infrared temperature sensor 503 passes through the shaped metal tube 502 and the connecting tube 501 in sequence, so that the shaped metal tube 502 and the connecting tube 501 play a role in protecting the wire 504. The upper end of the connecting tube 501 of this embodiment extends out of the connecting plate 206 through the corresponding assembly hole 207, and two locking nuts 505 are connected to the external thread of the connecting tube 501. The two locking nuts 505 are tightened on the upper and lower end surfaces of the connecting plate 206, thereby achieving the purpose of fixing the connecting tube 501 on the connecting plate 206.
