Description

Technical Field

[0001] The present invention relates to an alarm device, and more particularly, to a portable railway vehicle alarm instrument. Background Art

[0002] In the existing slag ladle car, there is no specially designed position for operators to stand and look out due to its running gear. Therefore, during the pushing and shunting operation of the slag ladle car, the shunter can only stand on the operating locomotive to look out. When there are many vehicles and passing through curves, there are blind spots for the shunter to observe the oncoming road conditions ahead. In order to enable the vehicles to pass each other smoothly, portable railway vehicle alarm instruments are equipped on all existing slag ladle cars. When the on-site visual environment is poor, the alarm instrument is placed on the outer side panel of the vehicle; after the on-site vision is restored, it is removed. This not only meets the passing requirements but also prevents the problem of potential safety hazards caused by the protruding external alarm instrument from the vehicle body after the vision is restored.

[0003] The traditional alarm instrument is magnetically adsorbed on the side panel of the vehicle. However, due to the poor on-site operating environment of the vehicle, rust is likely to appear on the vehicle body. If there is too much rust or debris on the side panel of the vehicle, it will lead to insufficient adsorption force of the alarm instrument and cause the alarm instrument to fall off, ultimately resulting in its damage. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a portable railway vehicle alarm instrument in view of the deficiencies of the prior art, which solves the problem of low reliability of the installation method of the alarm instrument by magnetic adsorption.

Specific embodiments

[0026] The following combines the embodiments to further describe the present invention, but does not constitute any limitation to the present invention. Any limited modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0027] Refer to Figures 1 - 6 , a portable railway vehicle alarm instrument of the present invention includes an alarm 1 and a box body 2 for installing the alarm 1. A power switch is installed on the side wall of the box body 2, and a storage battery 7 is installed in the box body 2. The storage battery 7 is electrically connected to the processing unit 8, the pressure strain gauge, and the electric slide rail 9 through a power switch 1 to realize power supply for the processing unit 8, the pressure strain gauge, and the electric slide rail 9. In addition, the storage battery 7 supplies power to the alarm 1 through a power switch 2.

[0028] A processing unit 8 is installed in the box body 2. Specifically, the processing unit 8 can be a control circuit based on a single-chip microcomputer. An operation handle 5 is fixedly provided on one side of the box body 2, and a plurality of pressure strain gauges are provided on the outer wall of the operation handle 5, and all the pressure strain gauges are electrically connected to the signal acquisition end of the processing unit. In addition, a button 1 and a button 2 are provided on the operation handle 5, and the button 1 and the button 2 are connected to the processing unit. Specifically, all the pressure strain gauges and the button 1 and the button 2 are respectively connected to the I / O pins on the single-chip microcomputer in a one-to-one correspondence, and the other ends of the button 1 and the button 2 are grounded.

[0029] When a staff member holds the operation handle 5, multiple pressure strain gauges on the operation handle 5 will be compressed and emit pressure signals; when stones or insects in the environment hit the operation handle 5, due to their small size, generally only one or two pressure strain gauges will be compressed and emit pressure signals. Therefore, the processing unit 8 of the present invention can judge whether the current compressed state of the operation handle 5 belongs to human grasping or external object hitting by monitoring the number of received pressure signals, effectively preventing the problem of misjudgment. The first button is used to combine with the pressure strain gauge to control the slider 10 of the electric slide rail 9 to move towards one end thereof; the second button is used to combine with the pressure strain gauge to control the slider 10 of the electric slide rail 9 to move towards the other end thereof. By combining the button with the pressure strain gauge, the problem of mis-triggering the electric slide rail 9 due to external object influence factors is further prevented, greatly improving the reliability of the installation of the alarm instrument.

[0030] Based on the above, the pressure strain gauges in this embodiment can be set to ten pieces, and both the inner and outer sides of the operation handle 5 need to be provided. According to the actual operation situation, the number of pressure strain gauges compressed at the same time can be set to five pieces, and the processing unit judges that it is currently manually grasped. If it is less than five pieces, it is judged as an external object hitting.

[0031] In addition, to prevent the problem that direct hitting of the pressure strain gauge by an external object may cause its damage, a rubber sheet is wrapped on the outside of the pressure strain gauge to play a role of buffering and protection.

[0032] One side of the box body 2 is fixedly installed with an installation box 3, one side of the installation box 3 is fixedly installed with a hook plate 4, and an L-shaped hanging plate 15 is fixedly installed on the outside of the railway vehicle for hanging the box body 2.

[0033] In this embodiment, the L-shaped hanging plate 15 is made of aluminum, which is beneficial to the light weight of the L-shaped hanging plate 15. Several reinforcing plates 16 are provided at the bending part of the L-shaped hanging plate 15, which can improve the rigidity of the L-shaped hanging plate 15.

[0034] A pushing mechanism is provided in the installation box 3, and a clamping end that can be movably inserted into the hook plate 4 is provided in the pushing mechanism. An electric slide rail 9 is installed in the installation box 3, the slider 10 of the electric slide rail 9 is connected to the pushing mechanism, and the control end of the electric slide rail 9 is electrically connected to the output end of the processing unit. That is, through the driving action of the electric slide rail 9 on the pushing mechanism, the clamping action of the hook plate 4 and the clamping end on the L-shaped hanging plate 15 is realized, thereby realizing the installation of the alarm instrument.

[0035] Specifically, the pushing mechanism includes a clamping block 12, a wedge block 11, and four tension springs 13. The clamping block 12 is slidably installed in the installation box 3. A through hole is provided on one side of the installation box 3 close to the hook plate 4. The clamping block 12 is located in the through hole, and the clamping block 12 serves as the clamping end of the pushing mechanism. The wedge block 11 is fixedly installed on the slider 10. One side of the clamping block 12 is provided with an inclined surface, and the inclined surface is in contact with the wedge surface of the wedge block 11. One ends of the four tension springs 13 are fixed in the installation box 3, and the other ends of the multiple tension springs 13 are fixed on the side wall of the clamping block 12.

[0036] When the slider 10 drives the wedge block 11 to move upward, the wedge block 11 exerts a pushing effect on the clamping block 12, causing the clamping block 12 to move towards the hook plate 4 and form a clamping effect on the L-shaped hanging plate 15 therein with the hook plate 4. And during the movement of the clamping block 12, the tension spring 13 is stretched, so that the tension spring 13 has a rebound potential energy. When the slider 10 moves downward and the inclined surface slides in contact with the wedge surface, the clamping block 12 will move towards the inside of the installation box 3 under the rebound action of the tension spring 13, thereby releasing the clamping on the L-shaped hanging plate 15.

[0037] To achieve a better clamping effect, anti-slip patterns are provided on the side of the clamping block 12 away from the wedge block 11. In addition, both the clamping block 12 and the wedge block 11 in this embodiment are made of aluminum, which is beneficial to the lightweight of the alarm instrument.

[0038] Considering the poor sliding performance between aluminum materials and the problem that the sliding performance is further reduced due to heat generation during the mutual sliding of aluminum materials, mirror stainless steel sheets are fixedly provided on both the inclined surface of the clamping block 12 and the wedge surface of the wedge block 11 to ensure the sliding performance between the clamping block 12 and the wedge block 11.

[0039] Two slide rails 14 are fixedly provided in the installation box 3 of this embodiment. The clamping block 12 is slidably connected to the slide rails 14, realizing the sliding installation of the clamping block 12. In addition, to prevent the problem that the clamping block 12 falls off the slide rails 14, the thickness of the clamping block 12 is set to be larger than the thickness of the wedge block 11 in this embodiment.

[0040] Preferably, rubber bands 6 are installed in the hook plates 4 on both sides of the clamping block 12. The rubber bands 6 have good elasticity and deformation ability. When the L-shaped hanging plate 15 is inserted into the hook plate 4, the rubber bands 6 will deform along the wall surface of the L-shaped hanging plate 15 towards the inside of the hook plate 4 under the guiding action of the L-shaped hanging plate 15, so that the rubber bands 6 have elastic potential energy. When the clamping block 12 releases the clamping on the L-shaped hanging plate 15, the rubber bands 6 will tend to return to their normal stretched state under the action of their elastic potential energy, so that the alarm instrument can be easily removed from the L-shaped hanging plate 15. Therefore, the setting of the rubber bands 6 serves to facilitate the removal of the alarm instrument.

[0041] The working principle of the present invention is as follows: When installing the alarm instrument, first turn on power switch 1 and power switch 2. Then hold the operation handle 5, align the hook plate 4 with the L-shaped hook plate 15 on the vehicle, and put the hook plate 4 onto the L-shaped hook plate 15 so that the L-shaped hook plate 15 is inserted into the hook plate 4. Then press button 1 to make the electric slide rail 9 operate, and its slider 10 drives the wedge block 11 to move upward. It should be noted here that Figure 2 the end of the hook plate 4 away from its opening is the upper end. That is, when the wedge block 11 moves upward, it means the wedge block 11 moves toward the upper end of the hook plate 4.

[0042] When the wedge block 11 moves upward, the wedge block 11 exerts a pushing effect on the clamping block 12, causing the clamping block 12 to move toward the hook plate 4. And during the movement of the clamping block 12, the tension spring 13 is stretched, so that the tension spring 13 has a resilience potential energy. When the clamping block 12 presses tightly on the L-shaped hook plate 15, the clamping block 12 and the hook plate 4 form a clamping effect on the L-shaped hook plate 15, completing the installation of the alarm instrument.

[0043] When the alarm instrument needs to be disassembled, hold the operation handle 5 and press button 2, so that the slider 10 of the electric slide rail 9 drives the wedge block 11 to move downward. When the slider 10 moves downward and the inclined surface slides in contact with the wedge surface, the clamping block 12 will move toward the inside of the installation box 3 under the resilience of the tension spring 13, thus releasing the clamping on the L-shaped hook plate 15. Then the alarm instrument can be taken off.

[0044] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can still be made, which will not affect the implementation effect of the present invention and the practicability of the patent.
