Description

Technical Field

[0001] The utility model embodiment relates to the technical field of rail detection, and in particular to a railway rail detection fixture. Background Art

[0002] With the rapid development of rail transit, the transport capacity and volume are constantly increasing, and the damage to the rails is also increasing. For this reason, sensors for monitoring rail damage are installed on the rail transit rails to detect the rails.

[0003] For example, a railway rail detection fixture disclosed in Chinese patent application number CN202322191894.4 has the following specific contents: before tightening the clamping nut, first install the laser sensor through the clamping groove, and drive the adjusting rod to slide synchronously in the installation groove by sliding the pressure rod upward or downward, so as to adjust the installation height of the laser sensor. After adjusting to a suitable angle, the clamp is fixed to the rail by tightening the clamping nut. During this process, the bolt can push the connecting plate and the pressure plate to slide in the cavity toward the adjusting rod, until the clamping nut is tightened, and the pressure plate is just pressed against the adjusting rod, thereby fixing the adjusting rod in the installation groove, and then clamping the laser sensor to the waist of the rail through the clamping groove, and finally achieving the purpose of adjusting the installation height of the laser sensor. It has the following technical problems:

[0004] Before tightening the clamping nut, in order to ensure that the installation height of the laser sensor does not change, it is necessary to always hold the laser sensor steady with one hand and turn the clamping nut with the other hand. Therefore, the installation operation of the laser sensor is inconvenient. Utility Model Content

[0005] To this end, an embodiment of the utility model provides a railway rail detection fixture to solve the problem that the installation operation of the laser sensor in the prior art is relatively complicated.

[0006] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0007] A railway rail detection fixture includes a clamping component 1 for cooperating with the rail to limit the position of a laser sensor;

[0008] A clamping component two for controlling the clamping component one to approach the rail is installed on the left side of the clamping component one, and a clamping component three is installed on the right side of the clamping component two.

[0009] The clamping component 1 includes a limit block, a connecting rod is installed at the lower end of the limit block, a positioning hole is opened at the left end of the connecting rod for facilitating the positioning of the height of the laser sensor in cooperation with the clamping component 2, a resistance plate 1 is installed at the lower end of the connecting rod, and a lead screw is movably installed on the left side of the resistance plate 1.

[0010] The clamping component 2 includes a locking rod for limiting the connecting rod, and the right end of the locking rod is telescoped in the hole cavity of the positioning hole, and a screw nut is installed on the left side of the locking rod for cooperating with the screw to control the contact plate 1 to move left and right, and a U-shaped plate is installed at the lower end of the screw nut for limiting the clamping component 3.

[0011] Furthermore, a slot is provided at the right end of the U-shaped plate, and a clamping block 1 is installed on the right end side wall of the U-shaped plate.

[0012] Furthermore, a limiting plate 1 is installed in the middle of the locking rod, and a spring 1 for controlling the locking rod to move rightward is connected to the left end of the limiting plate 1, and the spring 1 is located at the right end of the lead screw nut.

[0013] Furthermore, a second limiting groove is provided at the upper left end of the locking rod, and a first locking groove is provided at the bottom of the groove cavity of the second limiting groove.

[0014] Furthermore, a limiting plate three is installed on the upper end of the screw nut, and a sliding block for locking the locking rod is installed on the upper left end of the screw nut.

[0015] Furthermore, a clamping block 2 for engaging with a clamping slot 1 is installed at the lower end of the slider, and a spring 2 for cooperating with a limiting plate 3 to control the slider to move downward is installed at the upper end of the slider.

[0016] Furthermore, the clamping component three includes a contact plate two, a fixing block plugged into the slot is installed at the lower end of the contact plate two, and a card slot two for engaging with the card block one is formed at the upper end of the fixing block.

[0017] The utility model embodiment has the following advantages:

[0018] When installing the laser sensor, the height of the limit slot one is adjusted by extending and retracting the connecting rod inside the contact plate one to determine the installation height of the laser sensor. After the height of the limit block is confirmed, spring one pushes the limit plate one so that the locking rod is inserted into the cavity of the positioning hole to complete the locking of the installation height of the laser sensor. There is no need to hold the limit block. Finally, the laser sensor is placed in the cavity of the limit slot one, and the knob is turned to move the lead screw nut from the right side of the lead screw to the left side of the lead screw, thereby simultaneously driving the laser sensor to approach one side of the rail, and the side of the U-shaped plate where the clamping block one is installed simultaneously pushes the clamping component three, thereby finally completing the clamping and stabilization of the laser sensor.

When the laser sensor 20 is limited, the laser sensor 20 is clamped in the groove cavity of the limit groove 111.

[0035] The lower end of the limit block 110 is fixedly mounted with a connecting rod 120, and the left end of the connecting rod 120 is provided with a plurality of positioning holes 121 for locating the height of the laser sensor 20 in cooperation with the clamping assembly 200, and the lower end of the connecting rod 120 is provided with a contact plate 130 for limiting the connecting rod 120, and the connecting rod 120 slides up and down in the middle of the contact plate 130, and the middle of the contact plate 130 is provided with a groove for the connecting rod 120 to slide up and down, so as to adjust the height of the laser sensor 20. A lead screw 131 is movably mounted on the left side of the contact plate 130, and a knob 132 for controlling the rotation of the lead screw 131 is fixedly mounted on the left side of the lead screw 131.

[0036] By rotating the knob 132, the lead screw 131 is synchronously driven to rotate, so that the clamping component 200 moves from the right side of the lead screw 131 to the left side of the lead screw 131, and drives the clamping component 300 and the rail 10 to abut against each other. The clamping component 300 cooperates with the contact plate 1 130 to clamp the rail 10, so that the limit block 110 limits the rail 10.

[0037] A clamping assembly 200 for controlling the clamping assembly 100 to approach the rail 10 is installed on the left side of the clamping assembly 100. The clamping assembly 200 includes a locking rod 210 for limiting the connecting rod 120, and the right end of the locking rod 210 is retracted in the hole cavity of the positioning hole 121.

The slot cavity of the slot 214 is inclined, and the slot cavity opening faces the direction of the limiting plate 215. The left end of the block 241 is processed into an arc surface, so that when the lead screw nut 220 moves to the left, the block 241 moves from the right side of the slot cavity of the limiting groove 213 to the left side of the limiting groove 213, so that the spring 242 pushes the slider 240, the block 241 and the slot 214 are engaged, and the block 241 is not easy to move to the right, so that the lead screw nut 220 is not easy to slide from the left side of the lead screw 131 to the right side of the lead screw 131, thereby stabilizing the laser sensor 20.

[0040] A lead screw nut 220 is installed on the left side of the locking rod 210 for cooperating with the lead screw 131 to control the contact plate 130 to move left and right, a limit plate 3 221 is fixedly installed on the upper left end of the lead screw nut 220, a U-shaped plate 230 for limiting the clamping component 3 300 is fixedly installed on the lower end of the lead screw nut 220, a slot 231 is opened at the right end of the U-shaped plate 230, and a fixed block 320 is inserted into the groove cavity of the slot 231, a clamping block 1 232 is fixedly installed on the inner wall of the right end of the U-shaped plate 230 close to the clamping component 300, and the clamping block 1 232 and the clamping slot 2 321 are engaged with each other to lock the contact plate 2 310.

[0041] A slider 240 for locking the locking rod 210 is installed at the upper left end of the screw nut 220, and a block 241 for engaging with the slot 1 214 is fixedly installed at the lower end of the slider 240.

A short rod is fixed to the upper end of the slider 240, and the short rod is used to limit the slider 240. A limit plate 4 243 is fixedly installed on the upper end of the short rod, so that the spring 242 controls the slider 240 to move downward, driving the block 241 to engage with the slot 1 214, so that the screw nut 220 is not easy to loosen in the middle of the screw 131.

[0042] A clamping component three 300 is installed on the right side of the clamping component two 200, and the clamping component three 300 includes a contact plate two 310, and a fixing block 320 inserted into the slot 231 is fixedly installed at the lower end of the contact plate two 310, and a card slot two 321 for engaging with the card block one 232 is opened at the upper end of the fixing block 320.

When installing the laser sensor 20, the height of the limit slot 111 is adjusted by extending and retracting the connecting rod 120 inside the contact plate 130 to determine the installation height of the laser sensor 20. After the height of the limit block 110 is confirmed, the spring 1212 pushes the limit plate 121 so that the locking rod 210 is inserted into the cavity of the positioning hole 121 to complete the locking of the installation height of the laser sensor 20. Finally, the laser sensor 20 is placed in the limit slot 1 The groove cavity 111, by rotating the knob 132, the screw nut 220 moves from the right side of the screw 131 to the left side of the screw 131, and synchronously drives the laser sensor 20 to approach one side of the rail 10, and the side of the U-shaped plate 230 equipped with the clamping block 1 232 synchronously pushes the clamping component 3 300, so that the contact plate 2 310 cooperates with the contact plate 1 130 to clamp on both sides of the rail 10, through the engagement of the clamping block 241 and the clamping groove 1 214, when the limit block 110 presses the laser sensor 20 against the side of the rail 10, the screw nut 220 is not easy to move to the right side of the screw 131, so that the limit block 110 always stabilizes the laser sensor 20.
