Description

Technical Field

[0001] This utility model belongs to the field of height restriction frame technology, and specifically relates to an elastic buffer type bridge height restriction and anti-collision crossbeam device. Background Technology

[0002] Height restriction barriers are widely used on highways, urban roads and various other roads. Their main function is to limit the height of vehicles and ensure traffic safety.

[0003] Currently, height restriction barriers are mainly used for large vehicles. However, traditional height restriction barriers still have certain problems in use. For example, when some large trucks have their cargo loaded in the open in the cargo bed, if the driver is not sure of the exact height of the cargo, they will drive slowly when passing through the height restriction barrier to make it easier for the driver to stop in time if the vehicle cannot pass. When the height of the cargo is higher than the height restriction barrier, even if the truck is driving slowly, due to the weight of the truck, there will still be a certain braking distance when braking. This can easily cause the cargo to come into contact with the crossbeam of the height restriction barrier, causing hard damage to the crossbeam and reducing its service life. Utility Model Content

[0004] The purpose of this utility model is to provide an elastic buffer type bridge height limit anti-collision beam device, which has the advantages of buffering and easy installation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an elastic buffer type bridge height-limiting and anti-collision crossbeam device, comprising a crossbeam body, a connecting rod symmetrically slidably connected to the surface of the crossbeam body, buffer springs sleeved on the connecting rods symmetrically arranged on the front and back of the crossbeam body, mounting seats provided at both ends of the connecting rods, a buffer plate fixedly connected between the two mounting seats, grooves symmetrically opened on the surface of the mounting seats, a limit block provided inside the groove, a return spring engaged between the groove and the limit block, slots for insertion into the mounting seat at both ends of the connecting rod, a limiting groove communicating with the slot on the surface of the connecting rod, and a limiting groove engaged with the limiting block.

[0006] The above technical solution is as follows: This utility model has a connecting rod slidably connected to the main body of the crossbeam, and buffer plates lower than the main body of the crossbeam are installed on both sides of the connecting rod. The buffer plates serve as the height limit base. When a large vehicle passes through the height limit frame, it first contacts the buffer plate. If it cannot pass, the large vehicle will move the buffer plate a braking distance towards the buffer crossbeam, avoiding direct contact between the large vehicle and the main body of the crossbeam, thus preventing damage to the main body of the crossbeam and ensuring the service life of the main body of the crossbeam. The mounting base and the connecting rod are connected by a snap-fit ​​mechanism. After pressing the limiting block to retract into the groove, the mounting base can quickly remove the buffer plate from the connecting rod. When a large vehicle needs to pass through the height limit frame but cannot pass, there is no need to remove the main body of the crossbeam; simply removing the buffer plate is sufficient to complete the passage.

[0007] The present invention is further configured such that a chuck is symmetrically threaded onto the surface of the connecting rod, and the chuck is used in conjunction with a buffer spring.

[0008] The above technical solution involves limiting the buffer spring to facilitate the connecting rod's return to its original position.

[0009] The present invention is further configured such that the top and bottom of the mounting base plug end are equipped with sliding blocks, and the slot is provided with a sliding groove that is slidably connected to the sliding blocks.

[0010] The above technical solution involves sliding and limiting the insertion of the mounting base into the slot.

[0011] The present invention is further configured such that the surface of the limiting block is symmetrically fitted with sliders, and the interior of the groove is provided with a sliding groove that is slidably connected to the sliders.

[0012] The above technical solution is adopted: the limiting block is slidably limited.

[0013] The present invention is further configured such that both sides of the main body of the crossbeam are fixedly connected to a fixing sleeve, and a vertical beam is slidably sleeved inside the fixing sleeve.

[0014] The above technical solution facilitates the support and fixation of the main beam.

[0015] The present invention is further configured such that a limit bolt is threadedly connected to the surface of the fixed sleeve, and a limit hole is provided on the surface of the vertical beam to cooperate with the limit bolt.

[0016] The above technical solution is adopted to limit the position of the fixing sleeve.

[0017] The present invention is further provided that the bottom of the vertical beam is equipped with a mounting base, and the mounting base is provided with mounting holes.

[0018] The above technical solution facilitates the installation of vertical beams on the ground.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model has a connecting rod slidably connected to the main body of the crossbeam, and buffer plates lower than the main body of the crossbeam are installed on both sides of the connecting rod. The buffer plates serve as the height limit base. When the large vehicle passes through the height limit frame, it first contacts the buffer plate. When it cannot pass, the large vehicle will drive the buffer plate to move one braking distance towards the buffer crossbeam, avoiding the large vehicle directly contacting the main body of the crossbeam and causing damage to the main body of the crossbeam, thus ensuring the service life of the main body of the crossbeam.

[0021] 2. This utility model uses a snap-fit ​​connection between the mounting base and the connecting rod. After pressing the limiting block and retracting it into the groove, the mounting base can quickly remove the buffer plate from the connecting rod. When a large vehicle needs to pass through the height restriction frame but cannot pass, there is no need to remove the main body of the crossbeam. Simply remove the buffer plate quickly to complete the passage. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] refer to Figure 1 , Figure 4 and Figure 5The elastic buffer type bridge height-limiting and anti-collision crossbeam device includes a crossbeam body 1. Connecting rods 2 are symmetrically slidably connected to the surface of the crossbeam body 1. Buffer springs 3, fitted onto the connecting rods 2, are symmetrically arranged on both the front and back sides of the crossbeam body 1. A chuck 11 is symmetrically threaded onto the surface of the connecting rods 2. The chuck 11 works in conjunction with the buffer springs 3. By setting the buffer springs 3 and the chuck 11, the buffer springs 3 are limited, facilitating the return of the connecting rods 2 to their original position. Mounting seats 4 are provided at both ends of the connecting rods 2. Sliding blocks 12 are fitted at the top and bottom of the insertion end of the mounting seats 4. A sliding groove 13 is provided inside the slot 9, which slidably connects to the sliding block 12. By setting the sliding block 12 and the sliding groove 13, the device effectively limits the impact of the connecting rods 2. Mounting base 4 is inserted into slot 9 for sliding limit. Buffer plate 5 is fixed between the two mounting bases 4. Fixing sleeves 16 are fixedly connected to both sides of the main body of the crossbeam 1. Vertical beam 17 is slidably sleeved inside the fixing sleeve 16. By setting the fixing sleeve 16 and vertical beam 17, it is convenient to support and fix the main body of the crossbeam 1. Limit bolts 18 are threadedly connected to the surface of the fixing sleeve 16. Limiting holes 19 are opened on the surface of the vertical beam 17 to cooperate with the limit bolts 18. By setting the limit bolts 18 and limit holes 19, the position of the fixing sleeve 16 is limited. The bottom of the vertical beam 17 is equipped with a mounting base 20, and the mounting base 20 is provided with mounting holes. By setting the mounting base 20, it is convenient to install the vertical beam 17 on the ground.

[0031] Brief description of the usage process: When the large vehicle slowly passes through the height restriction frame, the large vehicle first contacts the buffer plate 5. This height restriction frame uses the buffer plate 5 as the height restriction basis. When the large vehicle cannot pass, the goods on the large vehicle contact the buffer plate 5 and drive the buffer plate 5 to move towards the buffer beam. There is a certain distance between the buffer plate 5 and the main body of the beam 1 to provide a buffer distance for the large vehicle to brake, avoid the large vehicle directly contacting the main body of the beam 1 and causing damage to the main body of the beam 1, and ensure the service life of the main body of the beam 1.

[0032] Example 2:

[0033] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The elastic buffer type bridge height limit and anti-collision crossbeam device includes a crossbeam body 1. A connecting rod 2 is symmetrically slidably connected to the surface of the crossbeam body 1. Buffer springs 3, which are sleeved on the connecting rods 2, are symmetrically arranged on the front and back of the crossbeam body 1. Mounting seats 4 are provided at both ends of the connecting rods 2. A buffer plate 5 is fixed between the two mounting seats 4. Grooves 6 are symmetrically opened on the surface of the mounting seats 4. Limiting blocks 7 are set inside the grooves 6. Slider blocks 14 are symmetrically assembled on the surface of the limiting blocks 7. Sliding grooves 15 are slidably connected to the sliders 14 inside the grooves 6. By setting sliders 14 and sliding grooves 15, the limiting blocks 7 are slidably limited. A return spring 8 is engaged between the grooves 6 and the limiting blocks 7. Slots 9 are opened at both ends of the connecting rods 2 to be inserted into the mounting seats 4. Limiting grooves 10, which communicate with the slots 9, are opened on the surface of the connecting rods 2. The limiting grooves 10 are engaged with the limiting blocks 7.

[0034] Brief description of the usage process: When a large vehicle needs to pass through the height restriction frame and is restricted by the buffer plate 5, such as some special vehicles, since the buffer plate 5 is lower than the main body of the crossbeam 1 and the buffer plate 5 is used as the height restriction line, it is only necessary to disassemble the buffer plate 5. Since the mounting seat 4 and the connecting rod 2 on the buffer plate 5 are snapped together, it is only necessary to use a pressing tool to press the limiting block 7 to remove it from the limiting groove 10, so that the limiting block 7 and the limiting groove 10 no longer restrict the mounting seat 4. The mounting seat 4 can be pulled out from the connecting rod 2 to complete the disassembly of the buffer plate 5, allowing the large vehicle to pass.
