Description

Technical Field

[0001] The utility model relates to the technical field of buffer structures, in particular to a buffer support structure for rail transportation. Background Art

[0002] Rail transit refers to a type of transportation tool or transportation system in which operating vehicles need to travel on specific tracks. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of train and railway technology, rail transit has shown more and more types, not only covering long-distance land transportation, but also widely used in medium and short-distance urban public transportation. In the installation of rail transit on-board equipment, a buffer support structure is required to facilitate the placement of rail transit on-board equipment.

[0003] The prior art discloses a buffer support structure for rail transit with application number CN202122261410.X. When the rail transit on-board equipment vibrates, the concave frame of the support structure is buffered on the load-bearing plate, and the load-bearing plate is buffered on the fixed seat through the second spring. At the same time, the load-bearing plate is buffered on the buffer plate through the buffer rod. The buffer plate drives the sliding sleeve to slide on the sliding rod, and then the buffer plate is buffered on the rubber spring. The synchronous buffer plate is buffered on the connecting plate through the first connecting block, the support rod and the second connecting block. The connecting plate drives the slider to slide in the slide groove through the first spring and offsets the vibration pressure above.

[0004] However, although the support structure can play a buffering role, it has no damping structure, resulting in excessive rebound force during shock absorption, which makes the vehicle-mounted equipment unstable. Secondly, the support structure can only play a role in buffering vibration force, and cannot assist in heat dissipation for the equipment, making the support function single. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a buffer support structure for rail transit to solve the technical problems in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a buffer support structure for rail transit, comprising a mounting plate, a fixed box is provided on the top of the mounting plate, and fixed frames are fixed on both sides of the mounting plate, one side of the fixed frame is connected to a fan plate through an elastic sheet, a connecting plate is connected to the lower part of the interior of the fixed box through a vertical spring, a second wedge block is connected to the two sides of the fixed box through a transverse spring, a first wedge block is fixed on both sides of the connecting plate, a mounting frame is fixed to the top of the connecting plate through a connecting rod, a piston cylinder is provided on the top of the fixed box, a piston plate is provided inside the piston cylinder, and a piston column is provided on the top of the piston plate, the top of the piston column is fixed to the mounting frame, an air intake pipe is provided on the outer surface and back of the piston cylinder, exhaust pipes are provided on both sides of the piston cylinder, and the exhaust pipes run through the bottom of the mounting frame.

[0007] Furthermore, the outer surfaces of the exhaust pipe and the intake pipe are both provided with one-way valves.

[0008] By adopting the above technical solution, the air flow direction of the exhaust pipe and the intake pipe can be controlled under the action of the one-way valve.

[0009] Furthermore, two sides of the fixed box are fixed to the second wedge block via telescopic rods.

[0010] By adopting the above technical solution, under the action of the telescopic rod, the second wedge block can stably move left and right.

[0011] Furthermore, a plurality of protrusions are provided at the lower part of the interior of the mounting frame, and the protrusions are made of rubber material.

[0012] By adopting the above technical solution, the multiple rubber protrusions can play a buffering purpose at one end, and can make a gap between the bottom of the vehicle-mounted equipment and the mounting frame, so as to facilitate air circulation when blowing.

[0013] Furthermore, a screw rod penetrates both the outer surface and the back of the mounting frame, and a clamping plate is fixed to one end of the screw rod.

[0014] By adopting the above technical solution, the rotation of the screw rod can move the clamping plate, and the traffic vehicle-mounted equipment can be clamped and fixed by the clamping plate.

[0015] Furthermore, a silicone pad is provided on one side of the clamping plate.

[0016] By adopting the above technical solution, the silicone pad can increase the friction between the clamping plate and the traffic vehicle-mounted equipment, and can also make the traffic vehicle-mounted equipment more stably fixed.

[0017] Furthermore, a knob is fixed to the other end of the screw rod.

[0018] By adopting the above technical solution, the staff can rotate the screw by turning the knob, which makes the operation more convenient.

[0019] Furthermore, the first wedge-shaped block and the second wedge-shaped block are in contact with each other, and both are made of rubber material.

[0020] By adopting the above technical solution, under the action of the rubber material, the friction between the first wedge block and the second wedge block is increased, thereby playing a damping role, so that the device can be slowly reset and the stability is improved.

[0021] Furthermore, the fan blades are provided in multiple groups, and the multiple groups of fan blades are distributed at equal intervals.

[0022] By adopting the above technical solution, multiple sets of fan blades will swing up and down under the action of vibration force, thereby accelerating the air circulation speed near the traffic vehicle-mounted equipment and achieving the purpose of cooling and heat dissipation.

[0023] In summary, the utility model mainly has the following beneficial effects:

[0024] 1. The utility model is provided with a vertical spring, a transverse spring, a first wedge block and a second wedge block. When vibration occurs, the connecting plate moves downward, and the vertical spring vertically buffers the vibration force. At the same time, the first wedge block squeezes the second wedge block, thereby causing the transverse spring to contract. The transverse spring buffers the vibration force laterally. Since the first wedge block and the second wedge block are made of rubber material, the friction between the two is relatively large, which plays a damping role, thereby preventing the spring reset force from being too large and affecting the stability of the equipment;

[0025] 2. The utility model is provided with a piston column, a piston plate, a piston cylinder, an air intake pipe, an exhaust pipe, a fixing frame, an elastic sheet and a fan sheet. When the traffic vehicle-mounted equipment vibrates up and down, the piston column drives the piston plate to make an up and down piston movement in the piston cylinder. When the piston plate moves upward, air enters the piston cylinder through the air intake pipe, and when the piston plate moves downward, the air is discharged through the exhaust pipe and blows toward the traffic vehicle-mounted equipment, thereby achieving the purpose of blowing air to the traffic vehicle-mounted equipment. In addition, since the traffic vehicle inevitably vibrates during driving, the vibration force will be directly transmitted to the mounting plate and the fixing frame. The vibration of the fixing frame will cause the fan sheet to cooperate with the elastic sheet to fan up and down, thereby accelerating the air circulation speed near the traffic vehicle-mounted equipment, achieving the purpose of auxiliary cooling and heat dissipation of the traffic vehicle-mounted equipment, and improving the functionality of the buffer support.

[0034] See also Figure 1-Figure 3 In the above embodiment, the outer surfaces of the exhaust pipe 20 and the intake pipe 19 are both provided with one-way valves, and the air flow directions of the exhaust pipe 20 and the intake pipe 19 can be controlled under the action of the one-way valves.

[0035] See also Figure 1-Figure 2In the above embodiment, a plurality of fan blades 6 are provided, and the plurality of fan blades 6 are evenly distributed. The plurality of fan blades 6 will swing up and down under the action of vibration force, thereby accelerating the air circulation speed near the traffic vehicle-mounted equipment and achieving the purpose of cooling and heat dissipation.

[0036] Embodiment 2: In order to improve the ventilation of the bottom of the vehicle-mounted equipment and improve the shock absorption effect, the embodiment 2 is improved on the basis of the embodiment 1. Figure 1-Figure 2 A plurality of protrusions 9 are provided at the lower part of the mounting frame 4, and the protrusions 9 are made of rubber material. The plurality of rubber protrusions can serve as a buffer at one end, and can provide a gap between the bottom of the vehicle-mounted device and the mounting frame, so as to facilitate air circulation when blowing.

[0037] Embodiment 3: In order to buffer the vibration force laterally and increase the damping effect, Embodiment 3 is improved on the basis of Embodiment 1. Figure 2 The first wedge block 13 and the second wedge block 14 are in contact with each other, and both are made of rubber material. Under the action of the rubber material, the friction between the first wedge block 13 and the second wedge block 14 is increased, thereby playing a damping role, so that the device can be slowly reset and the stability is improved.

[0038] See also Figure 2 In the above embodiment, both sides of the fixed box 2 are fixed to the second wedge block 14 through the telescopic rod 16. Under the action of the telescopic rod 16, the second wedge block 14 can stably move left and right.

[0039] Embodiment 4: In order to facilitate the clamping and fixing of the vehicle-mounted equipment, the fourth embodiment is improved on the basis of the first embodiment. Figure 1-Figure 2 The outer surface and the back of the mounting frame 4 are penetrated by a screw rod 7, and a clamping plate 8 is fixed at one end of the screw rod 7. The screw rod 7 is rotated to move the clamping plate 8, and the traffic vehicle equipment can be clamped and fixed by the clamping plate 8.

[0040] See also Figure 1-Figure 2 In the above embodiment, a silicone pad is provided on one side of the clamping plate 8. The silicone pad can increase the friction between the clamping plate 8 and the traffic vehicle equipment, and can also make the traffic vehicle equipment more stably fixed.

[0042] The implementation principle of the utility model is as follows: first, the staff places the vehicle-mounted equipment on the mounting frame 4, and then rotates the screw rod 7 so that the clamping plate 8 fixes the vehicle-mounted equipment. When vibration occurs, the connecting plate 11 moves downward, and the vertical spring 17 vertically buffers the vibration force. At the same time, the first wedge block 13 squeezes the second wedge block 14, so that the transverse spring 15 contracts, and the transverse spring 15 buffers the vibration force laterally. Since the first wedge block 13 and the second wedge block 14 are made of rubber material, the friction between the two is relatively large, which plays a damping role, avoiding the spring reset force being too large to affect the stability of the equipment, and when the traffic vehicle-mounted equipment vibrates up and down When the piston plate 18 moves, the piston column 21 drives the piston plate 18 to make an up and down piston movement in the piston cylinder 10. When the piston plate 18 moves upward, the air enters the piston cylinder 10 through the intake pipe 19, and when the piston plate 18 moves downward, the air is discharged through the exhaust pipe 20 and blows toward the traffic vehicle-mounted equipment, thereby achieving the purpose of blowing air to the traffic vehicle-mounted equipment. In addition, since the traffic vehicle inevitably vibrates during driving, the vibration force will be directly transmitted to the mounting plate 1 and the fixing frame 3. The vibration of the fixing frame 3 will cause the fan sheet 6 to cooperate with the elastic sheet 5 to fan up and down, thereby accelerating the air circulation speed near the traffic vehicle-mounted equipment, thereby achieving the purpose of assisting in cooling and dissipating the heat of the traffic vehicle-mounted equipment.
