Description

Technical Field

[0001] This utility model relates to the field of personnel carriers in horizontal tunnels, and specifically to a collision avoidance and buffer device for personnel carriers in horizontal tunnels. Background Technology

[0002] The horizontal tunnel personnel carrier is a non-powered rail vehicle used for transporting personnel in the horizontal tunnels of mines, and it needs to be pulled by a mining locomotive.

[0003] Chinese Patent Publication No. CN221757517U discloses an anti-collision buffer connection device for a vehicle in a flat lane, which relates to the technical field of anti-collision buffer connection devices. It includes a sleeve, a fixing block on one side of the sleeve, a shock-absorbing buffer structure for shock absorption between the fixing block and the sleeve, a first connector fixed at the end of the sleeve away from the fixing block, and a rotatable locking pin inserted into the fixing block.

[0004] The above-mentioned technical solution, a collision buffer connection device for personnel and vehicles in flat lanes, can achieve collision buffering through the cooperation between shock absorber springs and dampers. However, after long-term use, the performance of shock absorber springs and dampers may degrade, resulting in a decrease in the collision buffering effect. Furthermore, this device is inconvenient to disassemble and replace, lacking flexibility.

[0005] Therefore, a collision avoidance buffer device for pedestrians and vehicles in level lanes is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a collision avoidance buffer device for vehicles and pedestrians in level lanes, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A collision avoidance buffer device for personnel and vehicles in a level roadway includes two connectors, a connecting plate, and a stabilizing plate. A fixing plate is provided on the surface of each of the two connectors, and a reinforcing plate is provided on the surface of both connectors and the fixing plate. An installation mechanism for connecting and installing the fixing plate is provided on the connecting plate and the stabilizing plate, and a buffer mechanism for collision avoidance is provided on the connecting plate and the stabilizing plate.

[0009] Furthermore, the installation mechanism includes four positioning blocks, which are respectively fixedly installed on the surfaces of two fixed plates. Two positioning grooves are opened on the surfaces of the connecting plate and the stabilizing plate, and the positioning blocks are slidably installed on the inner wall of the positioning grooves.

[0010] Furthermore, each of the two fixing plates is provided with four bolts, and eight bolts are respectively provided on the connecting plate and the stabilizing plate.

[0011] Furthermore, the buffer mechanism includes a mounting plate, and a mounting groove is formed on the surface of the connecting plate, and the mounting plate is slidably mounted on the inner wall of the mounting groove.

[0012] Furthermore, the mounting plate is provided with two bolts, and the two bolts are located on the connecting plate.

[0013] Furthermore, a damping rod is fixedly installed on the surface of the mounting plate, and a buffer spring is sleeved on the outer wall of the damping rod. The buffer spring is disposed on the mounting plate and the telescopic cylinder. A telescopic cylinder is fixedly installed on the surface of the connecting plate, and the telescopic end of the damping rod and one end of the buffer spring are in contact with the telescopic cylinder.

[0014] Furthermore, a telescopic column is fixedly installed on the surface of the connecting plate, an adapter plate is fixedly installed on the telescopic end of the telescopic column, and the adapter plate is fixedly installed on the surface of the stabilizing plate. A rectangular plate is fixedly installed on the telescopic end of the telescopic cylinder, and a buffer pack is fixedly installed between the rectangular plate and the adapter plate.

[0015] Furthermore, the number of the telescopic columns is set to two, which are symmetrically distributed.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention, through the installation of mounting plates, telescopic columns, and telescopic cylinders, allows the second carriage to move forward under inertia when the first carriage brakes and stops, generating an impact force. A rubber buffer absorbs high-frequency vibration energy through molecular chain deformation, reducing direct collisions between metal parts. A buffer spring stores some impact energy through elastic deformation, and a damping rod converts the impact kinetic energy into heat dissipation through viscous fluid or friction elements, reducing the instantaneous impact load by more than 70%. Therefore, the combination of these three components reduces the maximum impact force between carriages to 1 / 5 of a purely rigid connection, achieving a collision-proof buffering effect. However, after a period of use, the performance of the damping rod and buffer spring will degrade, leading to a decrease in the collision-proof buffering effect. At this point, the fixing connection between the mounting plate and the connecting plate can be loosened by bolt two, allowing for disassembly and replacement. This provides collision-proof buffering between the first and second carriages and facilitates the installation and disassembly of the damping rod and buffer spring. The operation is simple and highly flexible.

[0018] This utility model, through the setting of positioning blocks and bolts, uses two positioning blocks inserted into two positioning slots to install and position the fixing plate with the connector head between them, and then uses four bolts to fix the fixing plate and the connecting plate together, thus fixing the connector head. The number of bolts improves the stability of the fixation. The same applies to the installation between the fixing plate and the stabilizing plate. Conversely, it can be disassembled, thus facilitating the installation and disassembly of the connector head. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. Example 1:

[0029] like Figure 1-4 As shown, a collision avoidance buffer device for personnel carriers in a level roadway includes two connectors 1, a connecting plate 4, and a stabilizing plate 7. The device is characterized in that a fixing plate 2 is provided on the surface of each of the two connectors 1, and a reinforcing plate 3 is provided on the surface of both connectors 1 and the fixing plate 2. An installation mechanism 5 for connecting and installing the fixing plate 2 is provided on the connecting plate 4 and the stabilizing plate 7. Figure 1-4 As shown, specifically, the installation mechanism 5 includes four positioning blocks 502, which are fixedly installed on the surfaces of the two fixing plates 2 respectively. Two positioning grooves 501 are opened on the surfaces of the connecting plate 4 and the stabilizing plate 7, and the positioning blocks 502 are slidably installed on the inner wall of the positioning grooves 501. Four bolts 503 are provided on each of the two fixing plates 2, and eight bolts 503 are respectively provided on the connecting plate 4 and the stabilizing plate 7.

[0030] More specifically, by setting up positioning blocks and bolts, two positioning blocks 502 are inserted into two positioning slots 501 to position the fixing plate 2 with connector 1 and the connecting plate 4. Then, four bolts 503 are used to fix the fixing plate 2 and the connecting plate 4, thus fixing the connector 1. The number of bolts 503 improves the stability of the fixation. The same applies to the installation between the fixing plate 2 and the stabilizing plate 7. Conversely, it can be disassembled, which facilitates the installation and disassembly of the connector 1. Example 2:

[0031] The connecting plate 4 and the stabilizing plate 7 are equipped with a buffer mechanism 6 for anti-collision buffering; such as Figure 1-4As shown, specifically, the buffer mechanism 6 includes a mounting plate 602, a mounting groove 601 is formed on the surface of the connecting plate 4, and the mounting plate 602 is slidably mounted on the inner wall of the mounting groove 601. Two bolts 605 are provided on the mounting plate 602 and are mounted on the connecting plate 4. A damping rod 603 is fixedly mounted on the surface of the mounting plate 602, and a buffer spring 604 is sleeved on the outer wall of the damping rod 603. The buffer spring 604 is mounted on both the mounting plate 602 and the telescopic cylinder 606. The surface of the connecting plate 4... A telescopic cylinder 606 is fixedly installed, and the telescopic end of the damping rod 603 and one end of the buffer spring 604 are in contact with the telescopic cylinder 606. A telescopic column 607 is fixedly installed on the surface of the connecting plate 4. An adapter plate 610 is fixedly installed on the telescopic end of the telescopic column 607, and the adapter plate 610 is fixedly installed on the surface of the stabilizing plate 7. A rectangular plate 608 is fixedly installed on the telescopic end of the telescopic cylinder 606. A buffer bag 609 is fixedly installed between the rectangular plate 608 and the adapter plate 610. The number of telescopic columns 607 is set to two, which are symmetrically distributed.

[0032] More specifically, the buffer pack 609 is made of rubber, and the two telescopic columns 607 provide limiting support. In use, the buffer spring 604 is fitted over the damping rod 603, with one end placed in the annular groove of the mounting plate 602 for positioning, ensuring the damping rod 603 is centered on the buffer spring 604. Then, it is inserted into the telescopic cylinder 606, so that the telescopic end of the damping rod 603 contacts the telescopic cylinder 606, while the other end of the buffer spring 604 enters the annular groove of the telescopic cylinder 606. Finally, the mounting plate 602 and the connecting plate 4 are fixedly connected using bolts 605, completing the installation. When the first car brakes to a stop, the second car will, due to inertia... When the impact force is generated, the material moves forward and generates an impact force. The rubber buffer 609 absorbs the high-frequency vibration energy through molecular chain deformation, reducing direct collision between metal parts. The buffer spring 604 stores some of the impact energy through elastic deformation. The damping rod 603 converts the impact kinetic energy into heat energy dissipation through viscous fluid or friction elements, reducing the instantaneous impact load by more than 70%. Therefore, the three components work together to reduce the maximum impact force between the carriages to 1 / 5 of that of a purely rigid connection, achieving a collision buffering effect. However, after a period of use, the damping rod 603 and the buffer spring 604 will experience performance degradation, resulting in a decrease in the collision buffering effect. At this time, the fixed connection between the mounting plate 602 and the connecting plate 4 can be released by bolt 2 605, allowing them to be disassembled and replaced.

[0033] In summary, during use, the two fixed plates 2 are fixedly connected to the connecting plate 4 and the stabilizing plate 7 through the installation mechanism 5, thus forming an integral structure. Then, by connecting the two connectors 1 to the two carriages respectively, traction conditions are formed. When the first carriage brakes and stops, the second carriage will move forward under the action of inertia. Under the action of the buffer mechanism 6, the impact force will be absorbed and consumed, achieving a collision-proof buffering effect. If the connector 1 wears out after long-term use, it can be removed and replaced through the installation mechanism 5. This achieves collision-proof buffering between the first and second carriages, and facilitates the installation and removal of the connector 1. The operation is simple and highly practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
