Description

Technical Field

[0001] This utility model relates to the field of lifting bollards, specifically a hydraulic split lifting bollard. Background Technology

[0002] Rising bollards, also known as retractable bollards, rising road bollards, anti-collision bollards, hydraulic rising bollards, and traffic control bollards, are widely used in urban traffic, gates and surrounding areas, pedestrian streets, highway toll stations, airports, schools, banks, large clubs, parking lots, and many other places. By restricting the passage of vehicles, they effectively ensure traffic order and the safety of key facilities and locations. Hydraulic rising bollards are automatic rising bollards powered by hydraulic motors, and they can be divided into integrated hydraulic rising bollards and split hydraulic rising bollards.

[0003] A Chinese patent, CN214939587U, discloses a hydraulic split-type lifting column. This patent includes a column body comprising an embedded body, a ground flange, and a column. The embedded body is located on the lower side of the column body, and a power cord interface pipe is located on the lower side of the front of the embedded body. The ground flange is located on the base surface of the embedded body, and the column is located inside the ground flange. An anti-collision ring is located on the inner wall of the ground flange, and a sealing ring is located at the connection between the anti-collision ring and the column. A first anti-slip groove is located on the base surface of the ground flange outside the anti-collision ring, and a second anti-slip groove is located on the base surface of the ground flange outside the first anti-slip groove. An aluminum top cover is located at the end of the column, and a first reflective strip is located on the upper side of the outer wall of the column below the aluminum top cover. The overall structure is simple, the anti-collision ring increases the overall impact resistance, and the overall practicality is higher.

[0004] The aforementioned disclosed patents have the following drawbacks:

[0005] (1) In the prior art, during the use of split hydraulic lifting rods, the lifting rod body needs to be repeatedly lifted and lowered. However, due to repeated friction between the inner rod and the outer shell during the lifting process, wear will occur on the surface of the connection, affecting its service life.

[0006] (2) Although the existing technology has a sealing ring at the connection of the lifting column to seal the connection, the sealing ring will age due to long-term outdoor environment. If it cannot be replaced in time, it will still cause a certain amount of water to accumulate inside the lifting column, which will affect the use of the lifting column.

[0007] (3) In the prior art, the lifting bollard placed outdoors will wear out due to the influence of the external environment, and since it is fixed in the ground, subsequent maintenance work is difficult to carry out.

[0008] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0009] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a hydraulic split lifting column.

[0010] To solve the above problems, this utility model proposes the following technical solution:

[0011] A hydraulic split lifting column includes: a cylinder, wherein a cavity is formed on the inner side of the cylinder and a through hole is formed on the bottom surface of the cylinder;

[0012] A connecting wire hole is located on one side of the upper end of the through hole, and the connecting wire hole is opened on one side surface of the cylinder.

[0013] A hydraulic drive mechanism is installed on the bottom surface inside the cylinder.

[0014] A connecting plate is mounted on the upper surface of the hydraulic drive mechanism;

[0015] A lifting column is fixedly connected to the upper surface of a connecting plate, and a reflective strip is installed on the upper end of the surface of the lifting column;

[0016] The first flange is fixedly connected to the upper surface of the cylinder, and connection holes are provided around the upper surface of the first flange.

[0017] The second flange is located inside the upper surface of the first flange. Countersunk screws are installed on the surface of the second flange, and the countersunk screws connect the first flange and the second flange.

[0018] An auxiliary ring is connected to the inner ring surface of the second flange. A grooved ring is provided on the inner side of the auxiliary ring, and a steel ball is installed on the inner side of the grooved ring.

[0019] Furthermore, a guide ring is fixedly connected to the bottom inner side of the cylinder, the lowest point of the guide ring is at the same height as the through hole, and multiple through holes are equidistantly arranged on the bottom surface of the cylinder.

[0020] Furthermore, a filter screen is fixedly connected to the inner side of each of the perforations.

[0021] Furthermore, the circumferential dimension of the connecting plate is larger than the inner ring dimension of the auxiliary ring.

[0022] Furthermore, a placement groove is provided on the inner side of the upper surface of the first flange, and the second flange is the same size as the placement groove, and the second flange is snapped into the inner side of the placement groove.

[0023] Furthermore, the auxiliary ring has an I-shaped structure, and a sealing ring one and a sealing ring two are fixedly connected to the upper surface of the auxiliary ring and one side of the upper surface, respectively.

[0024] Furthermore, there are multiple steel balls, which are equidistantly arranged circumferentially on the inner side of the grooved ring, and the steel balls are respectively attached to the lifting column and the grooved ring.

[0025] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0026] (1) The present invention provides an auxiliary ring at the connection between the second flange and the lifting column. A groove ring is opened on the inner side of the auxiliary ring, and multiple steel balls arranged in a circle are arranged on the inner side of the groove ring to ensure that the steel balls can fit with the lifting column.

[0027] (2) The present invention has a filter screen arranged in a circle on the bottom surface of the cylinder. Through the setting of the guide ring with a slope on the bottom surface of the cylinder, the water entering the cylinder can be guided through it and discharged from the bottom through the filter screen into the soil and absorbed by the soil, thereby avoiding the accumulation of water on the inside of the lifting column for a long time, which would damage the internal components.

[0028] (3) The present invention sets the first flange to fix the cylinder body through the embedded part, and the second flange to seal the cylinder body. The second flange can be removed at any time by countersunk screws, so that the internal components of the cylinder body can be operated more conveniently in the subsequent maintenance process, and the convenience of maintenance work is improved.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1 to 4 As shown, a hydraulic split-type lifting column includes a cylinder 1 with an inner cavity. A through hole 2 is provided on the bottom surface of the cylinder 1 to facilitate drainage of water inside. A connecting wire hole 3 is located on one side of the upper end of the through hole 2, allowing a signal wire to pass through and connect to the outer side. A hydraulic drive mechanism 4, installed on the bottom inner surface of the cylinder 1, drives a lifting column 6 mounted on its surface to rise and fall via a connecting plate 5 at the upper end. A reflective strip 601 is provided on the upper surface of the lifting column 6 to improve visibility at night. The first flange 7, fixed to the upper surface of the cylinder 1, has connection holes 701 around its upper surface to facilitate connection with the embedded body. The second flange 8, located inside the upper surface of the first flange 7, is connected to the first flange 7 by countersunk screws 801 to facilitate disassembly for subsequent maintenance. The auxiliary ring 9, connected to the inner ring surface of the second flange 8, has a grooved ring 901 on its inner side. The steel ball 902 installed inside the grooved ring 901 fits against the lifting column 6 to reduce friction between the two.

[0036] A guide ring 101 is fixed at the bottom inner side of the cylinder 1 so that the lowest point of the guide ring 101 is at the same height as the circularly arranged through holes 2.

[0037] Through the above technical solution, with the inclined setting of the guide ring 101, the water located inside the cylinder 1 can be discharged more smoothly from the through hole 2, avoiding the accumulation inside the cylinder 1 which is difficult to discharge.

[0038] A filter screen is installed inside the through hole 2.

[0039] Through the above technical solution, the filter screen set in the through hole 2 can block the external soil and prevent the external soil from entering the inside of the cylinder 1 through the through hole 2 during the water permeation process.

[0040] The circumferential dimension of the connecting plate 5 is larger than the inner ring dimension of the auxiliary ring 9.

[0041] Through the above technical solution, during the process of the connecting plate 5 being driven to rise by the hydraulic drive mechanism 4, the lifting column 6 on the upper surface is driven to rise and fall. The lifting height of the lifting column 6 is limited by the large circumference size to prevent it from falling out of the cylinder 1 due to excessive lifting height.

[0042] The placement groove 702 on the upper surface of the first flange 7 is the same size as the second flange 8, so that the second flange 8 can be snapped into the inside of the placement groove 702.

[0043] With the above technical solution, the placement groove 702 allows the second flange 8 to be placed inside it, thus facilitating the connection between the first flange 7 and the second flange 8.

[0044] The auxiliary ring 9 with an I-shaped structure has a sealing ring 903 and a sealing ring 904 respectively on its surface, so that the sealing ring 903 fits into the second flange 8 and the sealing ring 904 fits into the lifting column 6.

[0045] Through the above technical solution, with the setting of sealing ring 903 and sealing ring 904, the sealing performance of the connection is improved by fitting with the second flange 8 and the lifting column 6.

[0046] Multiple steel balls 902 arranged equidistantly in a circular pattern on the inner side of the groove ring 901 fit into the lifting column 6 and the groove ring 901.

[0047] With the above technical solution, the arrangement of the circumferentially arranged steel balls 902 reduces friction during repeated lifting and lowering by the rolling of the steel balls 902 during the lifting and lowering process of the lifting column 6 inside the auxiliary ring 9, thus avoiding excessive wear on the surface.

[0048] When using the hydraulic split-type lifting column, the user utilizes the connection hole 701 on the surface of the first flange 7 to allow the cylinder 1 to be connected to the underground via the pre-embedded parts. The second flange 8 is then passed through the lifting column 6 and placed inside the placement groove 702 on the surface of the first flange 7, and fixed with countersunk screws 801. During the lifting of the lifting column 6, the connecting wire of the hydraulic drive mechanism 4 can pass through the connecting wire hole 3 for connection. The hydraulic drive mechanism 4 drives the upper connecting plate 5 to rise and fall, thereby allowing the lifting column 6 to rise and fall. During the rising and falling process, the steel ball 902 inside the groove ring 901 of the auxiliary ring 9 fits against the lifting column 6, thereby reducing friction and surface wear. Water that enters the inside of the cylinder 1 is guided by the guide ring 101 and drained into the soil through the bottom through hole 2, preventing it from remaining inside the cylinder 1 for a long time.

[0049] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.
