Description

Technical Field

[0001] This invention relates to the field of traffic management equipment technology, specifically to a rising bollard, a bollard assembly, and a method for using the bollard assembly. Background Technology

[0002] Rising bollards are traffic control devices used to close off designated areas of access roads for traffic, landscaping, and public parking. Chinese invention patent CN 113668428 A discloses a rising bollard for road traffic, which solves traffic safety problems in the prior art. However, because this rising bollard uses an independent drive structure, it suffers from high cost and complex maintenance. Furthermore, since the motor and other drive and control components of the bollard are located at its bottom, the bollard is prone to water ingress or moisture, causing damage to the motor and other drive and control components. Summary of the Invention

[0003] The purpose of this invention is to provide a lifting bollard, a bollard assembly, and a method for using the bollard assembly, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A type of rising bollard assembly, installed on the ground in a vehicle traffic area to restrict vehicle passage, includes an outer cylinder fixed to the ground, an inner cylinder disposed inside the outer cylinder that can move vertically upward and downward, and a drive mechanism for driving the inner cylinder upward; the drive mechanism includes a pulley system and a traction rope passing over the pulley system; the traction end of the traction rope is connected to a winding and unwinding device; an elastic component connected in series with the traction rope is provided on the straight section of the traction rope; the elastic component is configured such that when the inner cylinder rises to its limit position or the inner cylinder is pressed down by an external force and cannot rise, the traction rope can continue to be wound by the winding and unwinding device until the elastic component is stretched to a set length by the traction rope.

[0006] Preferably, when the winding and unwinding device unwinds the traction rope, the inner cylinder can automatically descend and reset under its own gravity.

[0007] Preferably, a locking mechanism is provided between the outer cylinder and the inner cylinder. When the inner cylinder rises to its limit position, the locking mechanism locks the inner cylinder. After the positioning effect is released, the winding and unwinding device releases the traction rope, and the inner cylinder descends and resets under its own gravity.

[0008] Preferably, it further includes a limiting member fixed on the outer cylinder for limiting the stretching length of the elastic component, thereby limiting the stretching length of the elastic component to not exceed the maximum allowable stretching length of the elastic component.

[0009] Preferably, the outer cylinder is also fixed with a sensor switch for detecting that the elastic component has been stretched to a set length. When the sensor switch detects that the elastic component has been stretched to the set length, the winding and unwinding device stops winding the traction rope.

[0010] Preferably, one end of the traction rope is a traction end, which is connected to the winding and unwinding device; the other end of the traction rope is a fixed end and fixed at a preset anchor point. When winding the traction rope, the inner cylinder is driven to rise through the pulley block.

[0011] Preferably, one end of the elastic component is connected to the anchor point, and the other end is fixedly connected to the end of the traction rope.

[0012] Preferably, the anchor point is located at the bottom of the inner cylinder, the pulley block includes a fixed pulley fixed to the top of the outer cylinder, the traction rope starts from the anchor point, passes around the fixed pulley and connects to the take-up and release device, and the elastic component is located on the straight section of the traction rope between any two adjacent components of the anchor point, the fixed pulley and the take-up and release device.

[0013] Preferably, the anchor point is located at the top of one side of the outer cylinder, and the pulley group includes at least one pulley group consisting of a fixed pulley fixed at the top of the outer cylinder and at least one movable pulley fixed at the bottom of the inner cylinder. The traction rope starts from the anchor point, passes through at least one pulley group in sequence, and is then connected to the take-up and release device. The elastic component is located on the straight section of the traction rope between any two adjacent components of the anchor point, the fixed pulley, the movable pulley, and the take-up and release device.

[0014] Preferably, the anchor point is located at the bottom of the outer cylinder, and the pulley group includes at least one pulley group consisting of a fixed pulley fixed to the top of the outer cylinder and at least one movable pulley fixed to the bottom of the inner cylinder, as well as a reversing pulley located at the top of the outer cylinder for changing the direction of the traction rope. The traction rope starts from the anchor point, passes through the reversing pulley and at least one pulley group in sequence, and is then connected to the take-up and release device. The elastic component is located on the straight section of the traction rope between any two adjacent components of the anchor point, the reversing pulley, the fixed pulley, the movable pulley, and the take-up and release device.

[0015] Preferably, both ends of the traction rope are traction ends, and both ends of the traction rope are connected to the take-up and release device. The pulley block includes at least one pulley block consisting of a fixed pulley fixed to the top of the outer cylinder and at least one movable pulley fixed to the bottom of the inner cylinder, as well as a reversing pulley fixed to the top of the outer cylinder. The traction end of the traction rope starts from the take-up and release device, passes around the reversing pulley and at least one pulley block in sequence, and finally returns to the take-up and release device, forming a closed-loop transmission path. The elastic component is disposed on the straight section of the traction rope between any two adjacent components of the reversing pulley, the fixed pulley, the movable pulley, and the take-up and release device.

[0016] Preferably, when the traction rope passes around the pulley block, it first passes around the movable pulley and then around the fixed pulley.

[0017] A type of lifting bollard assembly includes multiple lifting bollards as described above. The traction ends of the traction ropes of each lifting bollard are combined in the same direction and connected to the same main rope. The main rope is connected to an external winding and unwinding device. When the winding and unwinding device winds up the main rope, it stops winding up the main rope when the elastic component of any lifting bollard is stretched to a set length.

[0018] Preferably, each of the lifting bollards is equipped with an induction switch on its outer cylinder to detect when the elastic component is stretched to a set length; when the induction switch of any lifting bollard detects that the elastic component of the lifting bollard has been stretched to the set length, it sends a signal and the winding and unwinding equipment stops winding the main rope.

[0019] A method for using a rising bollard assembly includes the following steps:

[0020] S1. In the initial state, the inner cylinder is located inside the outer cylinder, and the inner cylinder is at its lowest point; at this time, the winding and unwinding device is started, and the winding and unwinding device winds up the main rope, which drives the traction rope to move.

[0021] S2. After all the inner cylinders of the rising bollards have risen to their limit positions, the winding and unwinding equipment continues to wind up the main rope until the elastic component of any rising bollard is stretched to the set length, at which point the winding and unwinding equipment stops winding up the main rope.

[0022] During the above process, if the inner cylinder of any bollard is pressed down and cannot rise, and if the elastic component of any bollard is stretched to the set length, the winding and unwinding equipment will stop winding the main rope and issue an alarm to remind the staff to handle and / or unwind the main rope.

[0023] S3. When it is necessary to lower the inner cylinder, the winding and unwinding equipment releases the main winding rope and the traction rope, and the inner cylinder can automatically descend and reset under its own gravity.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] This invention uses a traction rope to drive the lifting and lowering of bollards, resulting in a relatively simple structure and low cost. The deployment and retrieval equipment can all be installed above ground, which is less prone to water ingress and moisture damage compared to the underground installation method in the prior art.

[0026] This invention, through the inclusion of an elastic component, allows the traction rope to continue winding by the take-up and release device even when the inner cylinder has risen to its limit position or is blocked by external force. The winding continues until the elastic component is stretched to a set length, at which point a sensor switch signals the take-up and release device to stop operating. This protects the equipment and prevents the traction rope from breaking or the device from being overloaded due to the device continuing to wind the rope after the inner cylinder has reached its limit position. Furthermore, the elastic component provides continuous elasticity after the inner cylinder has reached its limit position, ensuring stability once the inner cylinder is in place.

[0027] In this invention, the traction ropes of all rising bollards are wound synchronously. Due to the presence of elastic components, the stretching length of each elastic component by the traction rope may vary, which can compensate for the length error of the traction rope of each rising bollard during installation and operation. Under the premise of ensuring that each inner cylinder rises to the limit position, the connection between each traction rope and the main rope does not require precise length, thus reducing the difficulty of installation.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figure 1-10 In this embodiment of the invention, a lifting bollard includes an outer cylinder 1 fixed to the ground and an inner cylinder 2 disposed inside the outer cylinder 1 and capable of vertical lifting. A drive mechanism 3 for driving the inner cylinder 2 to rise is provided between the outer cylinder 1 and the inner cylinder 2. The drive mechanism 3 includes a pulley block and a traction rope 33. The traction end of the traction rope 33 is connected to a winding and unwinding device 5. An elastic component 4 connected in series with the traction rope 33 is provided on the straight section of the traction rope 33. When the winding and unwinding device 5 winds up the traction rope 33, the traction rope 33 drives the inner cylinder 2 to rise through the pulley block. When the inner cylinder 2 rises to its limit position or is pressed down by an external force and cannot rise, the traction rope 33 can continue to be wound up by the winding and unwinding device 5 until the elastic component 4 is stretched to a set length by the traction rope 33. When unwinding the traction rope 33, the inner cylinder 2 can automatically descend and reset under the action of gravity, or quickly descend and reset under the action of other elastic components. In this application, only the automatic reset of the inner cylinder 2 under the action of gravity is considered, and other situations are not considered.

[0042] This invention uses a traction rope to drive the lifting and lowering of the bollards, resulting in a relatively simple structure and low cost. Through the inclusion of the elastic component 4, when the inner cylinder 2 rises to its limit position or is blocked by external force, the traction rope 33 can continue to be wound up by the winding and unwinding device 5 until the elastic component 4 is stretched to a set length. This protects the relevant equipment and prevents the traction rope 33 from being directly broken or the winding and unwinding device 5 from being overloaded and damaged if the winding and unwinding device 5 continues to wind up after the inner cylinder 2 has risen to its limit position. Furthermore, when the inner cylinder 2 rises to its limit position, the elastic component 4 provides continuous elasticity, ensuring the stability of the inner cylinder 2 after it reaches its final position.

[0043] The length of the elastic component 4 after stretching does not exceed the maximum allowable stretching length of the elastic component 4; and the stretching deformation range of the elastic component 4 is configured not to interfere with the release and retraction of the traction rope 33.

[0044] It should be noted that the elastic component 4 in this invention is an elastically deformable component such as an elastic rope, a double-headed tension spring with hooks, or a spring sheet. In this invention, the preferred embodiment is a double-headed tension spring with hooks, with the hooks fixedly connected to the ends of the traction rope 33. Before the tension spring reaches its maximum extension length, the inner cylinder 2 rises and moves to a preset position. The maximum extension length of the tension spring does not exceed the maximum allowable extension length of the tension spring, i.e., the elastic limit of the tension spring. Once the extension length of the tension spring exceeds the elastic limit, plastic deformation will occur, leading to tension spring failure.

[0045] When selecting the elastic component 4, it is necessary to provide sufficient elastic force to support the inner cylinder 2 to be lifted to its limit position before reaching the maximum stretch length, so as to avoid the problem that the inner cylinder 2 cannot be lifted when the elastic component 4 is stretched to its maximum length.

[0046] The maximum working load Fmax of the tension spring is determined by the working conditions of the tension spring in the mechanism, but it should not reach its limit load Flim. Usually, Fmax should be kept at 0.8Flim.

[0047] To ensure the safety of the elastic component 4, a limiting member 12 is provided on the outer cylinder 1 to limit the deformation of the elastic component 4 from being stretched to its maximum allowable stretch length. Limiting the stretch length of the elastic component 4 can effectively prevent the elastic component 4 from being stretched beyond its elastic limit and failing.

[0048] Specifically, the limiting member 12 is a baffle with a through hole in the middle. The inner diameter of the through hole is not greater than the outer diameter of the tension spring. The traction rope 33 passes through the baffle through the through hole. When the tension spring is stretched, the traction rope 33 can move freely in the through hole until the end of the tension spring touches the baffle, thereby limiting the tension spring.

[0049] Alternatively, the outer cylinder 1 may be equipped with a sensor switch 13 for detecting when the tension spring has been stretched to a set length. When the sensor switch 13 detects that the tension spring has been stretched to the set length, it will issue an alarm signal and the take-up and take-down device 5 will stop working.

[0050] When the limiting member 12 and the inductive switch 13 are set at the same time, the inductive switch 13 is located on the outer cylinder 1 between the elastic member 4 and the limiting member 12. The inductive switch 13 acts as the first safety, limiting the extension length of the tension spring to not exceed the set length. The limiting member 12 acts as the second safety, directly blocking the end of the pull ring when the tension spring is pulled to the limiting member 12, so that the extension length of the tension spring does not exceed its maximum allowable extension length, thus avoiding the problem of the tension spring failing due to exceeding the elastic limit.

[0051] Specifically, the inductive switch 13 can be an electromagnetic proximity switch of model MC-18A in the prior art. This switch is waterproof and suitable for this equipment. During specific installation, the part that needs to be energized can be set at the limit member 12, while the part with the permanent magnet can be fixed to the end of the tension spring.

[0052] In this invention, the induction switch 13, the take-up and take-down device 5, and other components that require electricity are all connected to a dedicated control terminal and powered by the municipal power supply system. The control technology involved and the related components that need to be arranged are all existing mature technologies, and will not be described in detail here.

[0053] In this invention, the receiving and releasing devices and other equipment can be installed above ground, which is less likely to cause water ingress and moisture damage compared to the underground installation method in the prior art.

[0054] Based on the above technical solutions, the present invention may include the following implementation methods:

[0055] Example 1

[0056] Please see Figure 1 One end of the traction rope 33 is the traction end, and the other end of the traction rope 33 is the fixed end and is fixed at a preset anchor point 34. The anchor point 34 is set at the bottom of the inner cylinder 2, and a fixed pulley 31 is fixed at the top of the outer cylinder 1. The traction rope 33 starts from the anchor point 34, passes around the fixed pulley 31, and is connected to the take-up and release device 5. The elastic component 4 is set between the anchor point 34 and the fixed pulley 31 and / or between the fixed pulley 31 and the take-up and release device 5 on the straight section of the traction rope 33. In this embodiment, the preferred solution is that the elastic component 4 is fixed between the anchor point 34 and the fixed pulley 31. Specifically, the elastic component 4 is a tension spring, one end of which is fixed at the anchor point 34, and the other end of which is fixed to the end of the traction rope 33.

[0057] In this embodiment, the traction rope needs to bear the tension of the entire weight of the inner cylinder and the friction during operation, which requires high strength of the traction rope 33. Therefore, this is not the best embodiment of this application.

[0058] Example 2

[0059] Please see Figure 2 and Figure 3 One end of the traction rope 33 is the traction end, and the other end is the fixed end and fixed at the preset anchor point 34. The anchor point 34 is set on the top of one side of the outer cylinder 1. The traction rope 33 starts from the anchor point 34, passes through at least one pulley group consisting of a fixed pulley 31 and at least one movable pulley 32, and finally connects to the take-up and release device 5. When passing through the pulley group, it first passes through the movable pulley 32 and then passes through the fixed pulley 31.

[0060] The elastic component 4 can be set in any straight section of the traction rope 33. The straight section of the traction rope 33 includes the straight section of the traction rope 33 between the anchor point 34 and the movable pulley 32 of the first set of pulleys, between the movable pulley 32 and the fixed pulley 31 of the same set of pulleys, between the fixed pulley 31 of the previous set of pulleys and the movable pulley 32 of the next set, and between the last set of fixed pulleys 31 and the take-up and release device 5.

[0061] Please see Figure 4 When there are two or more movable pulleys 32 in the same pulley group, the movable pulleys 32 are set on the bottom surface of the inner cylinder 2, and the traction rope 33 holds the inner cylinder 2 through the movable pulleys, which can improve the stability of the inner cylinder 2 during the lifting process. At this time, the straight section of the traction rope 33 can also include the area between two adjacent movable pulleys 32 in the same pulley group; however, considering the distance between the movable pulleys 32, the elastic component 4 is usually not set here.

[0062] There is at least one elastic component 4. In this embodiment, the preferred option for the number of elastic components 4 is one, which is set between the anchor point 34 and the movable pulley 32 of the first set of pulleys. Specifically, the elastic component 4 is a tension spring, one end of which is fixed at the anchor point 34, and the other end of which is fixed to the end of the traction rope 33.

[0063] There is at least one set of pulley blocks. When there are two or more sets of pulley blocks, the inner cylinder 2 can be lifted with less effort according to the characteristics of the pulley blocks, and the load required by the take-up and take-down device 5 can be reduced. In this embodiment, the number of pulley blocks is preferably one set, and the movable pulley 32 in the pulley block is preferably one.

[0064] Based on Example 1, this solution can reduce the workload of the traction rope 33 by utilizing the characteristics of the movable pulley. However, the distance between the elastic component 4 and the movable pulley 32 is relatively short, making it difficult to meet the stretching requirements of the elastic component 4 in practical applications. Therefore, this solution is generally not considered in practical applications.

[0065] Example 3

[0066] Please see Figure 5 and Figure 6 As the preferred embodiment of this application, one end of the traction rope 33 is the traction end, and the other end is the fixed end and fixed at a preset anchor point 34. The anchor point 34 is set at the bottom of the outer cylinder 1. The top of the outer cylinder 1 is fixed with a reversing pulley 6 for changing the direction of the traction rope 33. Starting from the anchor point, the traction rope 33 passes through the reversing pulley 6, at least one pulley group consisting of a fixed pulley 31 and at least one movable pulley 32 in sequence, and finally connects to the take-up and release device 5. When passing through the pulley group, it passes through the movable pulley 32 first, and then passes through the fixed pulley 31.

[0067] The elastic component 4 can be set in any straight section of the traction rope 33. The straight section of the traction rope 33 includes the straight section of the traction rope 33 between the anchor point 34 and the deflecting pulley 6, between the deflecting pulley 6 and the moving pulley 32 of the first group of pulleys, between the moving pulley 32 and the fixed pulley 31 of the same group of pulleys, between the fixed pulley 31 of the previous group of pulleys and the moving pulley 32 of the next group, and between the last group of fixed pulleys 31 and the take-up and release device 5.

[0068] Please see Figure 7 When there are two or more movable pulleys 32 in the same pulley group, the movable pulleys 32 are set on the bottom surface of the inner cylinder 2, and the traction rope 33 holds the inner cylinder 2 through the movable pulleys, which can improve the stability of the inner cylinder 2 during the lifting process. At this time, the straight section of the traction rope 33 can also include the area between two adjacent movable pulleys 32 in the same pulley group; however, considering the distance between the movable pulleys 32, the elastic component 4 is usually not set here.

[0069] However, when two or more movable pulleys 32 are provided, since the movable pulleys 32 are located on both sides of the inner cylinder 2, a certain space is required between the outer cylinder 1 and the inner cylinder 2, which increases the overall volume of the equipment. Therefore, this solution is generally not considered in this embodiment. Figure 5 and Figure 6 The two options are better.

[0070] There is at least one elastic component 4. In this embodiment, the preferred option is to set one elastic component, which is set between the anchor point and the second deflecting pulley 6. Specifically, the elastic component 4 is a tension spring, one end of which is fixed at the anchor point 34, and the other end of which is fixed to the end of the traction rope 33.

[0071] In this embodiment, there is at least one set of pulleys. When there are two or more sets, the inner cylinder 2 can be lifted with less effort according to the characteristics of the pulleys, and the load required by the take-up and take-down device 5 can be reduced. However, the structure is more complicated. In this embodiment, the number of pulleys is preferably one set, and the movable pulley 32 in the pulley set is preferably one.

[0072] Example 4

[0073] Please see Figure 8 and Figure 9Both ends of the traction rope 33 are traction ends and connected to the take-up and release device 5. Its transmission path starts from the take-up and release device 5, passes sequentially through the reversing pulley 6 fixed at the top of the outer cylinder 1, at least one pulley group consisting of one fixed pulley 31 and at least one movable pulley 32, and finally returns to the take-up and release device 5, forming a closed-loop transmission path. The fixed pulley 31 is fixed at the top of the outer cylinder 1, and the movable pulley 32 is fixed at the bottom of the inner cylinder 2. When the traction rope 33 passes around the pulley group, it first passes around the movable pulley 32 and then around the fixed pulley 31. When the traction rope 33 is wound up, the two traction ends of the traction rope 33 move synchronously, which can effectively improve the winding efficiency of the traction rope 33 and increase the lifting speed of the lifting bollard.

[0074] The elastic component 4 can be set in any straight segment of the traction rope 33 in the transmission path. The straight segment of the traction rope 33 includes the straight segment of the traction rope 33 between the take-up and release device 5 and the first reversing pulley 6, between the first reversing pulley 6 and the moving pulley 32 of the first group of pulleys, between the fixed pulley 31 and the moving pulley 32 of the same group of pulleys, between the fixed pulley 31 of the previous group of pulleys and the moving pulley 32 of the next adjacent group of pulleys, and between the fixed pulley 31 of the last group of pulleys and the take-up and release device 5.

[0075] Please see Figure 10 When there are two or more movable pulleys 32 in the same pulley group, the movable pulleys 32 are set on the bottom surface of the inner cylinder 2, and the traction rope 33 passes through the bottom of the inner cylinder 2 to hold the inner cylinder 2, which can improve the stability of the inner cylinder 2 during the lifting process. At this time, the straight section of the traction rope 33 can also include the area between two adjacent movable pulleys 32 in the same pulley group; however, considering the distance between the movable pulleys 32, the elastic component 4 is usually not set here; in addition, in order to prevent the movable pulleys 32 from colliding with the bottom of the outer cylinder 1 when the inner cylinder 2 moves to the lowest point, it is possible to set the movable pulleys 32 at a position slightly above the bottom on both sides of the inner cylinder 2, and open through holes on the side wall of the inner cylinder 2 so that the traction rope 33 can pass directly through the bottom of the inner cylinder 2.

[0076] There is at least one elastic component 4. In this embodiment, the preferred option for the number of elastic components 4 is one, which is disposed between the take-up and release device 4 and the first deflecting pulley 6.

[0077] There is at least one set of pulley blocks. When there are two or more sets, the inner cylinder 2 can be lifted with less effort according to the characteristics of the pulley blocks, and the load required by the take-up and take-down device 5 can be reduced. In this embodiment, the number of pulley blocks is preferably one set, and the movable pulley 32 in the pulley block is preferably one.

[0078] In the scheme of embodiment 4, both ends of the elastic component 4 are provided with limiting components 12 and inductive switches 13.

[0079] It should be noted that an auxiliary lifting mechanism (not shown in the figure) can also be provided between the inner cylinder 2 and the outer cylinder 1 to assist the inner cylinder 2 in rising, so as to offset part of the weight of the inner cylinder 2 or the friction between the inner cylinder 2 and the outer cylinder 1 or the resistance of other components during operation, thereby reducing the workload of the launching and taking-up device 5.

[0080] The auxiliary lifting mechanism is preferably a spring, which is vertically disposed between the bottom of the inner cylinder 2 and the bottom of the outer cylinder 1, and provides an upward elastic force to the inner cylinder 2 when the inner cylinder 2 rises.

[0081] After the inner cylinder 2 moves into position, the launching and retracting device 5 in this application needs to fix the position of the inner cylinder 2. The positioning method can be to select a winch with a built-in mechanical locking structure, such as the DHQZ-500 electric winch of Donghong Lifting; or a locking mechanism can be set between the outer cylinder 1 and the inner cylinder 2. When the inner cylinder 2 rises to the limit position, the locking mechanism locks the inner cylinder 2; when the positioning effect is released, the inner cylinder 2 descends and resets under the action of gravity, or the inner cylinder 2 is pushed down quickly by other reset mechanisms. These reset mechanisms can be elastic components such as compression springs, gas springs, and hydraulic springs. Here, we only consider the automatic descent and reset of the inner cylinder 2 under the action of gravity, and the setting and selection of the reset mechanism will not be described in detail.

[0082] Please see Figure 11 The locking mechanism includes a locking tongue 7 that can be horizontally inserted into the inner cylinder 2 when the inner cylinder 2 is raised to a preset lifting position. The locking tongue 7 is slidably installed on the side wall of the top of the outer cylinder 1. A control device for driving the locking tongue 7 to insert or withdraw from the inner cylinder 2 is provided between the locking tongue 7 and the outer cylinder 1. The inner cylinder 2 is provided with a locking hole 8 corresponding to the locking tongue 7.

[0083] To ensure the stability of the locking tongue 7 during the sliding process, a groove 9 is provided on the top of the outer cylinder 1 for the locking tongue 7 to slide, and the control device is installed in the groove 9.

[0084] The control device is an electromagnetic actuator or an elastic reset mechanism, used to control the insertion or withdrawal of the locking tongue; specifically, it is a spring reset mechanism, including a spring 10 set in the slide groove 9. One end of the spring 10 is fixedly connected to the locking tongue 7, and the other end is fixed to the inner wall of the slide groove 9. In order to pull the locking tongue 7 out of the lock hole 8, a pull rope 11 is fixed to the tail end of the locking tongue 7. By pulling the rope, the locking tongue 7 can be pulled out of the lock hole 8, thereby releasing the locking effect of the locking mechanism.

[0085] The outer cylinder 1 is embedded in the ground of the passage area, and the top surface of the outer cylinder 1 is not higher than the ground. When the inner cylinder 2 is completely contained in the outer cylinder 1, it will not affect the passage of people and vehicles on the ground. Drainage holes are opened at the bottom of the outer cylinder 1 to prevent water from accumulating inside the outer cylinder.

[0086] Please see Figure 12Based on the above-mentioned lifting bollards, the present invention also discloses a lifting bollard assembly, wherein the traction ends of the traction ropes 33 of each lifting bollard are combined in the same direction and connected to the same main rope, and the main rope is connected to an external winding and unwinding device 5; when the winding and unwinding device 5 winds up the main rope until the elastic component 4 of any lifting bollard is stretched to a set length, the winding and unwinding device 5 stops winding up the main rope.

[0087] like Figure 1-12 As shown, each of the lifting bollards has an outer cylinder 1 equipped with an induction switch 13 that detects when the elastic component 4 is stretched to a set length; when the induction switch 13 of any lifting bollard senses that the elastic component 4 of the lifting bollard is stretched to a set length, it sends a signal and the winding and unwinding device 5 stops winding the main rope.

[0088] When there is an obstacle above the bollard, such as a vehicle, the inner cylinder 2 is pressed down and cannot rise. At this time, the winding and unwinding device 5 winds up the traction rope 33, and the elastic component 4 is stretched until the end of the elastic component 4 reaches the set position. The induction switch will still send a signal to make the winding and unwinding device 5 stop winding up the main rope.

[0089] In order to detect whether the inner cylinder 2 has risen to the limit position, a second sensor switch (not shown in the figure) is also installed between the inner cylinder 2 and the outer cylinder 1. If the sensor switch 13 senses that the elastic component 4 has been stretched to the set length, but the second sensor switch does not detect that the inner cylinder 2 has risen to the limit position, an alarm will be issued to remind the staff to handle the situation.

[0090] A method for using a rising bollard assembly includes the following steps:

[0091] S1. In the initial state, the inner cylinder 2 is located inside the outer cylinder 1, and the inner cylinder 2 is at its lowest point; at this time, the winding and unwinding device 5 is started, the winding and unwinding device 5 winds up the main rope, and the main rope drives the traction rope 33 to move.

[0092] S2. After all the inner cylinders 2 of the lifting bollards have risen to their limit positions, the winding and unwinding device 5 continues to wind up the main rope until the elastic component 4 of any lifting bollard is stretched to the set length, at which point the winding and unwinding device 5 stops winding up the main rope; during the above process, if the inner cylinder 2 of any lifting bollard is pressed down and cannot rise, and the elastic component 4 of any lifting bollard is stretched to the set length, the winding and unwinding device 5 stops winding up the main rope and issues an alarm to remind the staff to handle and / or unwind the main rope;

[0093] S3. When it is necessary to lower the inner cylinder 2, the winding and unwinding device 5 releases the main winding rope and the traction rope 33, and the inner cylinder 2 can automatically descend and reset under its own gravity.

[0094] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Furthermore, the contents not described in detail in this specification are all prior art known to those skilled in the art.
