Description

Technical Field

[0001] The utility model relates to an adjustable height-limiting frame, in particular to an adjustable height-limiting frame with buffer protection. Background Art

[0002] Transportation refers to the industry engaged in the transportation of passengers and goods, and the transmission of language, text and images, including transportation and postal and telecommunications. It belongs to the tertiary industry in the national economy. In order to prevent vehicles from being over-height or overloaded on traffic roads and bridges, height limit devices are set up to ensure the safety of traffic roads and bridges.

[0003] For example, Chinese patent publication number CN218322486U discloses a height-limited frame that is easy to adjust in height, which relates to the technical field of height-limited frames. The height-limited frame that is easy to adjust in height includes a first support frame and a second support frame. Fixed beams are arranged on the tops of the first support frame and the second support frame. Both ends of the fixed beams are fixedly connected to the first support frame and the second support frame through beam fixing supports, and an adjustable beam is arranged below the fixed beam; both ends of the adjustable beam are fixed on the inner sides of two height adjustment components. When the height-limited frame is adjusted to a limited height, the motor transmits power to the reducer.

[0004] However, in the above scheme, when a vehicle accidentally collides with the height-limiting crossbeam, it is not convenient to provide buffering protection for the height-limiting crossbeam, which may easily cause damage to the height-limiting frame, thereby affecting road traffic and being not very convenient.

[0005] Based on the above situation, the utility model proposes an adjustable height limit frame with buffer protection to alleviate the situation where the height limit frame is damaged due to collision. Utility Model Content

The height of the height-limiting rod is adjusted by rotating the screw rod on one side, and the movable rod on the other side rises and falls accordingly to control the height of the overall height-limiting frame, and the buffer device provides buffering for collision through the elasticity of the spring.

[0009] Furthermore, a fixing block is provided between the screw rod and the height limiting rod, the fixing block is provided with an installation cavity, a motor is provided in the installation cavity, and the motor is connected to the screw rod. The screw rod is driven to rotate by the forward and reverse rotation of the motor to realize the lifting and lowering of the height limiting rod.

[0010] Furthermore, the movable rod is provided with a support rod, the support rod is provided with a sliding groove, a sliding rod is provided in the sliding groove, and one end of the sliding rod is connected to the height-limiting rod through a support block. The height is interactively adjusted as the height rod is raised or lowered.

[0011] Furthermore, the foot is provided with a mounting hole, and the connection between the foot and the movable pole and the vertical pole is provided with reinforcing ribs respectively. The mounting hole of the foot is suitable for fixing in various venues, and the reinforcing ribs prevent the movable pole and the vertical pole from tilting and deflecting.

[0012] Furthermore, a connecting rod is provided on the fixing plate, and the connecting rod is connected to a height-limiting sign, which is used to identify the height limit of the current height-limiting frame.

[0013] Furthermore, the height limit rod is provided with a fixing rod, the buffer device is provided with a protective plate, one side of the protective plate is provided with a reflective strip or a rubber pad, the other side is provided with a buffer rod, and the top of the buffer rod is provided with a limit block, which abuts against the spring in the fixing rod. The reflective strip effectively serves as a visual warning, and the limit block at the top of the buffer rod prevents the buffer rod from being pushed out of the fixing rod by the spring.

[0014] Furthermore, a limit plate is provided at one end of the screw rod to prevent the motor from rotating and causing the screw rod to rotate away from the fixed plate, and at the same time limit the maximum height of the height-limiting frame.

[0023] See also Figure 1 , Figure 3-4The anti-collision buffer device includes three fixed rods 21, and the three fixed rods 21 are fixedly connected to the side wall of the height limiting rod 8. The three fixed rods 21 are provided with a buffer cavity 22, and the three buffer cavities 22 are slidably connected to the limit blocks 23. The side walls of the three limit blocks 23 are fixedly connected with springs 19, and one end of the three springs 19 is fixedly connected to the side wall of the height limiting rod 8. The side walls of the three limit blocks 23 are fixedly connected with buffer rods 20, and the three buffer rods 20 respectively penetrate the side walls of the corresponding fixed rods 21, and one end of the three buffer rods 20 is fixed together. A protective plate 17 is connected. When a vehicle accidentally collides with the height limit pole 8, the vehicle will first hit the protective plate 17, and the protective plate 17 can initially buffer the impact force of the collision. Then the protective plate 17 will squeeze the three buffer rods 20. The three buffer rods 20 squeeze the three springs 19 through the three limit blocks 23. The three springs 19 can buffer the impact force of the collision for a second time, thereby buffering and protecting the height limit pole 8, which can greatly reduce the impact force on the height limit pole 8, thereby reducing the degree of damage to the height limit pole 8 and avoiding affecting traffic.

[0024] See also Figure 1 , Figure 3 The side wall of the protective plate 17 is provided with a rubber pad, which can buffer the impact force of the collision, and can also protect the surface of the protective plate 17 and the paint of the vehicle.

[0028] The working principle of the utility model is as follows: first, the height limit frame can be installed on the road where the height limit is required by passing the bolts through the mounting holes 2.

The screw 15 can drive the motor 10 to move upward when rotating, and the motor 10 drives the fixing block 9 to move, and the fixing block 9 drives the height limit rod 8 to move. The height limit rod 8 drives the sliding rod 6 to slide in the sliding groove 4 through the support block 7, so that the height limit rod 8 is driven to move up and down by starting the motor 10. , thereby adjusting the height of the height limit pole 8. When a vehicle accidentally collides with the height limit pole 8, the vehicle will first hit the protective plate 17, and the protective plate 17 can initially buffer the impact force of the collision, and then the protective plate 17 will squeeze the three buffer rods 20. The three buffer rods 20 squeeze the three springs 19 through the three limit blocks 23. The three springs 19 can perform secondary buffering on the impact force of the collision, thereby buffering and protecting the height limit pole 8, which can greatly reduce the impact force on the height limit pole 8, thereby reducing the degree of damage to the height limit pole 8 and avoiding affecting traffic.
