Description

Technical Field

[0001] This utility model relates to the field of road management roadblock technology, specifically to a liftable access control roadblock bollard. Background Technology

[0002] Road bollards, as a common traffic management facility, are widely used in urban roads, residential entrances and exits, parking lots, scenic spots, and other places. Their main function is to effectively manage and control the entry and exit of vehicles and pedestrians. By installing multiple road bollards in a parallel, equidistant array, access rights in specific areas can be restricted, ensuring safety and order within the area, preventing unauthorized vehicles from entering at will, and also guiding traffic flow when necessary, thus improving the efficiency of traffic management.

[0003] Currently, there are many types of bollards available, which can be broadly categorized into fixed and adjustable types based on their structure and function. Fixed bollards are typically installed directly on the ground with a fixed height and width, making them difficult to modify once installed and serving only as a barrier. Adjustable bollards, on the other hand, offer some degree of height adjustment. They generally use an internal lifting mechanism to raise and lower the top of the bollard. When allowing vehicles to pass, the top of the bollard is lowered to be level with the ground; when restricting traffic, the top is raised to create a barrier. However, most existing adjustable bollards still have the following drawbacks in practical use:

[0004] 1. Most adjustable bollards can only adjust the height and cannot restrict the passage width, which makes them difficult to meet the actual needs in some scenarios where vehicle width needs to be restricted;

[0005] 2. The overall structure of traditional bollards is usually fixed to the ground foundation. When the lifting components, adjustment mechanisms and other parts inside the bollard are damaged and need to be repaired or replaced, it is often necessary to destroy the ground around the bollard in order to disassemble the entire bollard, which is extremely inconvenient for maintenance. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a liftable access control bollard, which solves the problems mentioned in the background art.

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

[0008] A type of liftable access control bollard includes a base shell for pre-embedding into the ground, with an equipment compartment on the top and a flange inserted into the equipment compartment via a detachable connection. A lifting cavity extending through the bottom of the flange is opened on the top of the flange, and a lifting assembly is installed at the bottom of the inner side of the lifting cavity. A U-shaped column frame is installed on the top of the lifting assembly, with the outer side wall of the column frame fitting against the inner side wall of the lifting cavity. A top cover assembly that fits against the top of the flange is fixedly installed on the top of the column frame. When the top cover assembly fits against the top of the base shell, it can seal the top opening of the lifting cavity.

[0009] Width-limiting wing plates are hinged at the bottom of the top cover assembly and inside the column frame. An adjustment mechanism acting on the two width-limiting wing plates is installed on the column frame to drive the two width-limiting wing plates to achieve the following two working states:

[0010] In the first state, both width-limiting wing plates are horizontal, and the free ends of the two width-limiting wing plates are located on the side where the two width-limiting wing plates are far apart from each other, and the free ends of the two width-limiting wing plates extend to the outside of the top cover assembly.

[0011] Second state: Both width-limiting wing plates are vertical, and both width-limiting wing plates are hidden inside the column frame.

[0012] This utility model provides a retractable access control bollard. Compared with the prior art, it has the following advantages:

[0013] 1. When components mounted on the flange are damaged and require disassembly and repair, personnel can pull the flange out of the equipment compartment to remove it, thereby allowing for the repair of the components on the flange. This eliminates the need to damage the ground outside the base housing before disassembling the base housing and to disassemble the entire bollard, facilitating the repair of the bollard. Furthermore, through the design of the width-limiting wing plate and adjustment mechanism, the bollard can be raised to form a road barrier while simultaneously limiting the width of road traffic according to usage requirements, thus improving its applicability.

[0014] 2. Through the design of the top cover assembly, which includes a pressure-bearing top plate and a protective cover, when the linear actuator is damaged and cannot lift the column frame upwards while the pressure-bearing top plate is in contact with the flange, the protective cover can be removed from the pressure-bearing top plate, and the flange can be pulled out from the equipment compartment for disassembly, which facilitates the disassembly and maintenance of the linear actuator.

[0015] 3. By setting up inspection hole plugs, the inspection hole plugs can cover the bolt channel, improve the overall aesthetics, and effectively prevent debris from entering the bolt channel. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] To address the technical problems in the background section, the following is proposed as a retractable access control bollard:

[0024] As one embodiment of this utility model, combined with Figure 1 - Figure 4As shown, the present invention provides a lifting access control bollard, including a base shell 1 for pre-embedding into the ground, an equipment compartment 11 on the top of the base shell 1, a flange 12 detachably installed on the top of the base shell 1 and inserted into the equipment compartment 11, a lifting cavity 121 penetrating through the bottom of the flange 12, a lifting assembly 2 installed at the bottom of the inner side of the lifting cavity 121, a column frame 3 with a U-shaped longitudinal section installed on the top of the lifting assembly 2, the outer side wall of the column frame 3 and the inner side wall of the lifting cavity 121 are in contact with each other, and a top cover assembly 4 that can be in contact with the top of the flange 12 is fixedly installed on the top of the column frame 3. When the top cover assembly 4 is in contact with the top of the base shell 1, the top cover assembly 4 seals the top opening of the lifting cavity 121.

[0025] The bottom of the top cover assembly 4 and the inner side of the column frame 3 are both hinged with width-limiting wing plates 5. The column frame 3 is equipped with an adjustment mechanism 6 that acts on the two width-limiting wing plates 5. The adjustment mechanism 6 allows the two width-limiting wing plates 5 to have two states:

[0026] In the first state, both width-limiting wing plates 5 are horizontal, the free ends of the two width-limiting wing plates 5 are located on the side of the two width-limiting wing plates 5 that are far apart from each other, and the free ends of the two width-limiting wing plates 5 extend to the outside of the top cover assembly 4.

[0027] Second state: Both width-limiting wing plates 5 are vertical and both width-limiting wing plates 5 are hidden inside the column frame 3. Specifically, when installing the base shell 1, a foundation pit is first dug on the ground at the installation location, the base shell 1 is inserted into the foundation pit, and then concrete is backfilled to fix the base shell 1.

[0028] Understandably, when components mounted on flange 12 are damaged and require disassembly and repair, personnel can remove flange 12 from equipment compartment 11 for disassembly, thus allowing for the repair of components on flange 12 without damaging the ground outside base housing 1 and disassembling the base housing 1, or disassembling the entire roadblock post, facilitating the repair of the roadblock post. When adjusting the height of the roadblock post to restrict normal road traffic, the lifting assembly 2 moves the column frame 3 upward, causing the top cover assembly 4 to move upward, so that the two width-limiting wing plates 5 are above flange 12, thereby raising the roadblock post to form a roadblock. When adjusting the roadblock post to limit road traffic width, the adjusting mechanism 6 sets the two width-limiting wing plates 5 to a first state, with the free ends of both width-limiting wing plates 5 extending to the outside of the top cover assembly 4, achieving the effect of adjusting the width of the roadblock post, thus achieving the effect of limiting road traffic width and improving applicability.

[0029] Combination Figure 2As shown, the adjustment mechanism 6 includes a guide bracket 61, a guide rail 62, a slider 63, a wing plate connecting rod 64, and a wing plate drive assembly 65. The guide bracket 61 is fixedly installed on the inner bottom wall of the column frame 3 between the two opposite sides of the width-limiting wing plates 5. The top of the guide bracket 61 is symmetrically fixed with vertical guide rails 62. Slider 63 is slidably installed on the two guide rails 62 along the axis of the guide rails 62. Wing plate connecting rods 64 are hinged to both sides of the slider 63. The other ends of the two wing plate connecting rods 64 are respectively hinged to the two width-limiting wing plates 5. The wing plate drive assembly 65, which acts on the slider 63, is installed on the guide bracket 61 to make the slider 63 slide along the two guide rails 62 or stop sliding.

[0030] Combination Figure 3 As shown, the wing drive assembly 65 includes a threaded rod 651 that is vertically rotatably mounted on a guide bracket 61. The threaded rod 651 is threadedly connected to the slider 63. A motor 652 for driving the threaded rod 651 to rotate is fixedly mounted on the guide bracket 61. The output shaft of the motor 652 is coaxially fixedly connected to the threaded rod 651.

[0031] Combination Figure 4 As shown, the lifting assembly 2 includes a cylinder mounting plate 21 fixedly installed at the bottom of the lifting cavity 121 by screws. A vertically oriented linear actuator 22 is fixedly installed on the top of the cylinder mounting plate 21. Both the linear actuator 22 and the motor 652 are powered by an external power source and controlled by an external controller. The installation structure of the linear actuator 22 and the motor 652 being electrically connected to the external power source is prior art and falls within the scope of knowledge for those skilled in the art, and will not be described in detail here. The piston of the linear actuator 22... The rod is fixedly installed with a lifting platform 23, and the column frame 3 is placed on top of the lifting platform 23. The lifting platform 23 and the column frame 3 are fixed together by screws. Specifically, when the piston rod of the linear actuator 22 slides outward along its cylinder to the limit state, the bottom end of the column frame 3 is located inside the lifting chamber 121. When using the linear actuator 22, personnel use tools to remove the screws used to fix the cylinder mounting plate 21, and then remove the screws used to fix the lifting platform 23 and the column frame 3, so that the linear actuator 22 can be disassembled and repaired.

[0032] Combination Figure 1As shown, a flange 122 is integrally formed at the top of the outer wall of the flange 12. When the flange 12 is inserted into the equipment compartment 11, the bottom of the flange 122 fits against the top of the base housing 1. Vertical anchor bolts 123 are movably inserted through the flange 122 in a rectangular array on the outer side of the flange 12. The bottom of the anchor bolts 123 is threaded through the top of the base housing 1. Specifically, a receiving hole is formed in a rectangular array on the flange 122 on the outer side of the flange 12. Four anchor bolts 123 are movably inserted through the bottom of the receiving hole in a vertical direction. The bottom of the anchor bolts 123 is threaded through the bottom of the receiving hole and connected to the base housing 1. When the anchor bolts 123 are threaded to the base housing 1, they are hidden inside the receiving hole.

[0033] Combination Figure 2 As shown, the top cover assembly 4 includes a pressure-bearing top plate 41 fixedly connected to the top of the column frame 3. Specifically, two width-limiting flanges 5 are symmetrically hinged to the bottom of the pressure-bearing top plate 41. The pressure-bearing top plate 41 can fit against the top of the flange 12 and seal the top of the lifting cavity 121. When the pressure-bearing top plate 41 fits against the top of the flange 12, the pressure-bearing top plate 41 is located between the four anchor bolts 123. A protective cover 42 is installed on the top of the pressure-bearing top plate 41 and is fitted over it. The thickness of the protective cover 42 is five centimeters. When the protective cover 42 fits against the top of the flange 12, it does not affect the normal passage of vehicles. When the protective cover 42 is fitted over the outside of the pressure-bearing top plate 41, the protective cover 42... The bottom is on the same horizontal plane as the bottom of the pressure plate 41, and the protective cover 42 is fixed to the pressure plate 41 by the wing plate locking bolt 43. Specifically, when the pressure plate 41 is attached to the top of the flange 12, the protective cover 42 blocks the top of multiple receiving holes. Through the design of the top cover assembly 4 including the pressure plate 41 and the protective cover 42, when the pressure plate 41 is attached to the flange 12 and the linear actuator 22 is damaged and cannot lift the column frame 3 upward, the protective cover 42 can be removed from the pressure plate 41, and the flange 12 can be pulled out from the equipment compartment 11 for disassembly, which facilitates the disassembly and maintenance of the linear actuator 22.

[0034] Combination Figure 3As shown, both sides of the protective cover 42 are provided with horizontal bolt channels 421. There are two wing plate locking bolts 43, which move horizontally through the two bolt channels 421 respectively. One end of the wing plate locking bolt 43 passing through the bolt channel 421 is threaded horizontally through the pressure-bearing top plate 41, and the other end of the wing plate locking bolt 43 can be hidden inside the bolt channel 421. An inspection hole plug 422 for sealing the bolt channel 421 is inserted on the protective cover 42 and inside the bolt channel 421. By setting the inspection hole plug 422, the inspection hole plug 422 achieves the effect of covering the bolt channel 421, improving the overall aesthetics, and effectively preventing debris from entering the bolt channel 421.

[0035] Working principle and usage process of this utility model:

[0036] 1. Installation Process

[0037] First, excavate a pit in the ground, place the base shell 1 inside, and flush the top with the ground. Then, backfill with concrete to secure it. After the concrete has hardened, insert the flange 12, which has been fitted with the lifting assembly 2, the column frame 3, and the top cover assembly 4, into the equipment compartment 11. Once the flange flange 122 is flush with the top of the base shell 1, use four anchor bolts 123 to pass through the receiving holes of the flange flange 122 and thread them onto the base shell 1 to complete the installation of the bollard.

[0038] 2. Raise the roadblocks

[0039] When it is necessary to restrict road traffic, the linear actuator 22 is activated via an external controller. The piston rod of the linear actuator 22 extends and pushes the column frame 3 and the top cover assembly 4 upward through the lifting platform 23, raising the road barrier post above the ground to form an obstacle.

[0040] 3. Expand the width limiting function

[0041] If additional width restriction is required, motor 652 can be started via an external controller. Motor 652 drives threaded rod 651 to rotate, causing slider 63 to slide upward along guide rail 62. Slider 63 pushes two width-limiting wing plates 5 to rotate outward around the hinge point via wing plate connecting rods 64 at both ends, so that their free ends extend horizontally outward from the outside of top cover assembly 4, thereby achieving width restriction.

[0042] 4. Retract the roadblocks

[0043] When the restriction is lifted, first control motor 652 to reverse, causing slider 63 to move down. This pulls the width-limiting wing plate 5 back to a vertical position via wing plate connecting rod 64, where it is hidden inside the column frame 3. Then control linear actuator 22 to retract the piston rod, causing the entire column frame 3 to descend until the pressure-bearing top plate 41 of the top cover assembly 4 is in contact with the top of flange 12, and the road barrier post is lowered to be level with the ground.

[0044] 5. Inspection and maintenance

[0045] When components on flange 12 (such as linear actuator 22) are damaged and require repair, first remove the inspection hole plugs 422 on both sides of the protective cover 42, remove the wing plate locking bolts 43, and remove the protective cover 42. Then remove the four anchor bolts 123, and the entire flange 12 can be pulled out of the equipment compartment 11, facilitating the repair or replacement of internal components such as the lifting assembly 2 without damaging the surrounding ground and base housing 1.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
