Description

Technical Field

[0001] The utility model relates to the technical field of railway end collision prevention, in particular to an end line intelligent alarm collision prevention device. Background Art

[0002] During the operation of the railway shunting end line, the operator guides the train at the rear of the train, manually judges the distance between the locomotive and the anti-collision block (car blocker), and notifies the driver to brake through the radio. However, due to the limitations of line conditions (such as curves, etc.), the influence of fog, snow and rain, the intermittent observation of the operator, and improper speed control, it is easy to cause shunting derailment accidents that collide with the car block and cross the terminal. According to statistics, such accidents have occurred in major technical stations and some intermediate stations across the railway, and many stations have also experienced such accidents one after another, which not only caused great economic losses, but also had a great impact on transportation production. Shunting end line operation accidents account for a large proportion of railway safety accidents, which will not only interrupt railway transportation and seriously affect the operation of the transportation system, but also cause the loss of people's lives and property.

[0003] There are existing technologies for anti-collision at the end of railways: Patent CN108099960A discloses an anti-collision system for railway shunting end line operations, and its technical solution includes the technical feature of using sensors set on the rails to obtain the position and speed of the train;

[0004] Another example is the prior art CN 214565378 U, a railway end line anti-collision system, which mainly includes a train sensing device, an information processing device and a train onboard device.

[0005] The above-mentioned end-of-road anti-collision technical solution adopts a series of sensor technical solutions, but its most important device structure is still installed on the railway line. Although the above-mentioned technical solution can achieve the functions of warning and early warning, the anti-collision device installed on the railway line will still be affected. For example, vehicles that are out of time or do not receive signals cannot stop in time, which will still cause impact and damage to the anti-collision device.

[0006] In view of this, the present utility model is proposed. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a dead-end line intelligent alarm and anti-collision device, which solves the problems raised in the above-mentioned background technology.

[0009] An end-line intelligent alarm and anti-collision device comprises: a buckle box, a locking hole is provided on the side of the buckle box, a locking bolt is inserted in the inner cavity of the locking hole, a telescopic hole is provided on one side of the top of the locking bolt, a locking column is inserted in the inner cavity of the telescopic hole, an arc box is fixedly connected to the top of the locking column, an extrusion wheel is rotatably installed in the inner cavity of the arc box through a horizontal axis, a vertical groove is provided on the inner wall of the telescopic hole, a clamping groove is provided on one side of the bottom of the locking bolt, a limiting protrusion is fixedly connected to the outer wall of the locking column, and a locking spring is mounted on the outer ring of the locking column.

[0010] Preferably, the top of the locking spring is pressed against the bottom of the outer wall of the arc box, and the bottom of the locking spring is pressed against the top of the locking bolt.

[0011] Preferably, the vertical groove is a strip groove that runs through the entire telescopic hole.

[0012] Preferably, the clamping groove is communicated with the inner cavity of the telescopic hole, and the depth of the clamping groove is the same as the height of the limiting protrusion.

[0013] Preferably, a pull ring is fixedly connected to the bottom of the locking column.

[0014] Preferably, the top of the buckle box is fixedly connected to a vertical pole, a bracket is fixedly mounted on the outer wall of the vertical pole, a sensor is mounted on the bracket, and a warning light is mounted on the top of the vertical pole.

[0015] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0016] 1. The end-of-line intelligent alarm anti-collision device can realize the rapid disassembly and assembly of the anti-collision device through the design and use of the buckle box, locking bolt, locking column, locking spring and extrusion wheel, and compared with the installation method of bolt fasteners in the prior art, the damage to the track is smaller.

[0017] 2. The end-of-line intelligent alarm anti-collision device, through the design and use of the rotatable extrusion wheel, has a sliding friction between the entire anti-collision device and the track, so it can move backward when hit, that is, the impact force can be converted into energy, thereby protecting the anti-collision device and various components thereon.

[0018] The specific implementation modes of the present utility model are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The utility model is now described in further detail with reference to the accompanying drawings.

[0029] See also Figure 1-4 As shown, in this embodiment, an end-line intelligent alarm and anti-collision device is provided, including a buckle box 1 for installation on a track, locking holes 2 are opened on both side surfaces of the buckle box 1, a locking bolt 3 is inserted in the inner cavity of the locking hole 2, a telescopic hole 9 is opened on one side of the top of the locking bolt 3, a locking column 4 is inserted in the inner cavity of the telescopic hole 9, an arc box 6 is fixedly installed on the top of the locking column 4, an extrusion wheel 7 is rotatably installed in the inner cavity of the arc box 6 through a horizontal axis, vertical grooves 10 are opened on both sides of the inner wall of the telescopic hole 9, a clamping groove 11 is opened on one side of the bottom of the locking bolt 3, and a limiting protrusion 5 matching the vertical groove 10 and the clamping groove 11 is fixedly welded on the outer wall of the locking column 4, and a locking spring 8 is mounted on the outer wall of the locking column 4.

[0030] The vertical groove 10 is a strip groove that runs through the entire telescopic hole 9 , and the depth of the clamping groove 11 is the same as the height of the limiting protrusion 5 .

[0031] The top of the locking spring 8 is pressed against the outer wall of the arc box 6 , and the bottom of the locking spring 8 is pressed against the top of the locking bolt 3 .

[0032] A pull ring 16 is fixedly welded to the bottom of the locking column 4 .

[0033] In this embodiment, Figure 1-4 As shown, in actual use, the entire buckle box 1 is directly buckled on the track, and then the locking bolt 3 is pushed in the direction of the track until one end of the locking bolt 3 is against the side of the track. At this time, the limiting protrusion 5 on the locking column 4 is stuck in the clamping groove 11, and the locking spring 8 is in an extremely compressed state. Then, the finger hooks the pull ring 16, and the locking column 4 is driven to move downward through the pull ring 16. When the limiting protrusion 5 is out of the clamping groove 11, the locking column 4 is rotated so that the limiting protrusion 5 on the locking column 4 is in the same position as the vertical groove 10, and then the pull ring 16 is released. The locking spring 8 will instantly push the extrusion wheel 7 upward and squeeze it at the lower edge of the protruding part of the rail, thereby realizing the rapid installation of the anti-collision device.

[0034] At the same time, the extrusion wheel 7 is designed to be rotatable. When a vehicle fails to stop in time and hits the anti-collision column device, the impacted anti-collision device will move backward along the guide rail. The sliding friction between the rotatable extrusion wheel 7 and the rail can effectively reduce the impact damage caused by the impact force.

[0035] Embodiment 2:

The alarm device includes an audible and visual alarm, i.e., a speaker structure, and a warning light 15 is installed on the top of the vertical pole 12.

[0037] In this embodiment, during actual use, the pressure of the wheelset of the locomotive vehicle is sensed to activate the sound and light alarm and transmit the "stop" command at the same frequency as the railway wireless shunting light display equipment, so as to realize active safety protection for the vehicle picking and delivering operations at the end line of the railway, and to prevent accidents of collision with the soil barrier to the greatest extent. Two sensors are installed at a fixed position in front of the car stop at the end line (one position and two positions, one position sensor is for the direction of the oncoming vehicle, and two position sensor is close to the line terminal, the same below). When the wheelset of the locomotive vehicle triggers the one-position sensor, the sound and light alarm system starts working; when the wheelset of the locomotive vehicle triggers the two-position sensor, the "stop" command at the same frequency as the wireless shunting light display equipment is transmitted.

[0038] At the same time, the rangefinder can monitor the distance of the approaching vehicle in real time, so as to realize timely alarm action, wherein the alarm action transmits signals to the control room and the vehicle in the form of horn sound, warning light 15 and the same number transmitter.
