Description

Technical Field

[0001] This utility model relates to the field of railing gate technology, specifically a railing gate installation device. Background Technology

[0002] A crane is a heavy-duty piece of equipment that uses mechanical structures to lift and move heavy objects horizontally. A gate is a mechanical gate component that combines passage and safety protection functions. A gate installation device is a set of mechanical components used to precisely fix the gate to the target carrier and ensure the effective realization of its protective and passage functions. However, the existing gate installation method requires welding the main beam to the main beam and the walkway railing or end beam during the main beam manufacturing process. It is an integral and non-removable structure, which is labor-intensive and difficult to manufacture, repair, or replace, and is not conducive to mass production and inventory. However, a new type of crane gate structure with announcement number CN218809964U can be shipped with the main beam or separately. After arriving at the site, it can be tightened with U-shaped mounting bolts. The installation is simple and convenient. When the gate needs to be replaced or repaired due to problems, the repair and replacement work is also more convenient, improving the efficiency of installation and maintenance.

[0003] While the aforementioned technology facilitates installation and improves installation and maintenance efficiency, it suffers from a problem: once the gate is installed, it cannot effectively secure the gate when closed. During crane operation, the vibrations from the crane are transmitted to the gate, causing it to shake and continuously collide with the limit switch. This can lead to the limit switch's internal contacts suddenly disconnecting due to vibration, resulting in a sudden power outage during normal crane operation. Furthermore, it significantly reduces the lifespan of the limit switch. Utility Model Content

[0004] The purpose of this utility model is to provide a railing gate installation device to solve the problem mentioned in the background art that current railing gate installation devices on the market cannot effectively stabilize the railing gate when it is closed after installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a railing gate installation device, comprising an installation strip, with hinges installed on the upper and lower parts of the installation strip, a railing gate body installed on one side of each hinge, a limit switch installed at one end of the installation strip, a contact block installed at one end of the railing gate body, support plates at both ends of one side of the installation strip, and limit plates at both ends of one side of the railing gate body. Limit blocks are slidably connected inside both limit plates. Slots adapted to the limit blocks are respectively opened inside the two support plates. A sliding rod is provided at one end of each of the two limit blocks. A stabilizing component for securing the railing gate body is provided on the support plate, and a fixing component for fixing the installation strip is provided on the installation strip.

[0006] Preferably, the stabilizing component includes four fixing blocks respectively disposed at both ends of the two support plates, and each of the four fixing blocks has a support member at the end away from the support plate. The two support members on both sides are rotatably connected by a rotating shaft, and the outer surface of the two rotating shafts is provided with a bending member.

[0007] Preferably, each of the two bending members has a wedge-shaped block at one end, and each of the two bending members has a protrusion at the end near the limiting block. A torsion spring is provided between each end of the two rotating shafts and one end of the four supporting members.

[0008] Preferably, the fixing component includes two connecting blocks respectively disposed at both ends of the mounting strip on the side away from the gate body, the outer surfaces of the two connecting blocks are slidably connected with mounting blocks, and the two mounting blocks and the two connecting blocks are respectively provided with locking bolts at both ends.

[0009] Preferably, a baffle is provided at one end of the upper part and one end of the lower part of the railing gate body, and a magnetic strip is provided at the end of the mounting strip and the railing gate body away from the baffle, and the two magnetic strips are attracted to each other.

[0010] Preferably, one end of each of the two limiting blocks is wedge-shaped, and the end of each of the two slide rods away from the limiting blocks is provided with a pull ring.

[0011] Preferably, both of the sliding rods have a fixed plate slidably connected to the outer surface of the railing gate body, and a spring is provided between one end of the two fixed plates and one end of the two limiting blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By closing the gate body, the contact block and limit switch are activated, thus controlling the opening and closing of the crane. This restricts the crane's starting conditions, prevents accidental injuries or fatalities, and eliminates core safety hazards.

[0014] By setting up stabilizing components, the barrier gate body can be stably supported when closed, ensuring that the contact block is always in close contact with the limit switch sensing end, thus ensuring that the limit switch can be stably triggered and completely avoiding power interlock failure in the half-triggered state.

[0015] By using the fixed components, the installation strip can be fixedly installed in the appropriate position on the crane. It can be precisely fixed in the preset position to ensure that the railing gate rotates smoothly around the hinge and can accurately fit the end beam frame after closing, avoiding the use affected by trajectory deviation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides the following technical solution: a railing gate installation device;

[0025] Example 1: To address the problem that existing railing gate installation devices cannot effectively secure the railing gate when it is closed after installation, a solution is disclosed: A mounting strip 1, with hinges 2 installed at both the upper and lower parts of the mounting strip 1 (e.g., ...). Figure 1 As shown), the gate body 3 is used to rotate the gate body 3. The gate body 3 is installed on one side of the hinge 2. A limit switch 4 is installed on one end of the mounting strip 1. A contact block 5 is installed on one end of the gate body 3. Support plates 6 are provided at both ends of one side of the mounting strip 1. Limit plates 7 are provided at both ends of one side of the gate body 3. Limit blocks 8 are slidably connected inside the two limit plates 7 (such as...). Figure 4 and Figure 6As shown), the two support plates 6 have slots inside that are adapted to the limiting blocks 8. Each of the two limiting blocks 8 has a sliding rod 9 at one end. The support plates 6 are equipped with a stabilizing assembly for securing the gate body 3. The stabilizing assembly includes four fixing blocks respectively located at both ends of the two support plates 6. Each of the four fixing blocks has a support member 10 at the end furthest from the support plate 6. A rotating shaft 11 is rotatably connected between the two support members 10 on both sides. A bending member 12 is provided on the outer surface of each of the two rotating shafts 11. A wedge-shaped block 13 (such as...) is provided at one end of each of the two bending members 12. Figure 5 and Figure 6 As shown), both bending pieces 12 have protrusions 14 near the limiting block 8, and torsion springs are provided between the two ends of the two rotating shafts 11 and one end of the four supporting pieces 10, respectively. A baffle 15 is provided at one end of the upper and lower parts of the gate body 3 (as shown). Figures 2-4 As shown), the mounting strip 1 and the railing gate body 3 are both equipped with magnetic strips 16 at the ends away from the baffle 15, and the two magnetic strips 16 are magnetically attracted to each other. One end of each of the two limit blocks 8 is wedge-shaped, and the ends of each of the two slide rods 9 away from the limit blocks 8 are equipped with pull rings for pulling the slide rods 9. The outer surfaces of the two slide rods 9 are slidably connected to a fixing plate set on one side of the railing gate body 3, and springs are provided between one end of each of the two fixing plates and one end of each of the two limit blocks 8.

[0026] Install the gate body 3 onto the mounting strip 1 using hinge 2, and then install the limit switch 4 onto the mounting strip 1. Next, electrically connect the limit switch 4 to the crane's power supply. When the gate body 3 is open, rotate it to bring the two magnetic strips 16 closer together. Under magnetic force, the gate body 3 is limited to its open state. At this time, the contact block 5 is not in contact with the limit switch 4, and the crane will not start. When closing the gate body 3, rotate it to move the two magnetic strips 16 away from each other (e.g., ...). Figure 1 (As shown), then the limiting block 8 will contact the support plate 6. Subsequently, under the action of the wedge-shaped surface of the limiting block 8, the sliding rod 9 will slide, compressing the spring. When the limiting block 8 contacts the slot, the spring will release its elastic force to reset, thereby driving the limiting block 8 into the slot (as shown). Figure 4 and Figure 6 As shown), this limits the movement of the gate body 3. At this time, the contact block 5 will contact the limit switch 4 and start the crane. When the limit block 8 approaches the support plate 6, it will also contact the protrusion 14 and push the protrusion 14 and the bending piece 12, which will then drive the rotating shaft 11 and the torsion spring to rotate. Subsequently, the bending piece 12 will also drive the wedge block 13 to fit against the other side of the gate body 3, thus providing stable support for the gate body 3. When it is necessary to release the limit of the gate body 3, the pull ring (such as...) can be pulled. Figure 4 and Figure 6As shown), this causes the sliding rod 9 and the limiting block 8 to slide. At this time, the wedge-shaped surface of the limiting block 8 contacts the protrusion 14. As the limiting block 8 moves continuously, the protrusion 14 no longer contacts the limiting block 8, and then the torsion spring is no longer under force and resets, so that the gate body 3 can rotate.

[0027] Example 2: Unlike Example 1, the fixing components can be used to fix the mounting strip 1 in place. The example discloses that the mounting strip 1 is provided with fixing components, which include two connecting blocks 17 respectively located at both ends of the mounting strip 1 on the side away from the gate body 3 (e.g., ...). Figure 1 and Figure 2 As shown), mounting blocks 18 are slidably connected to the outer surfaces of the two connecting blocks 17. Locking bolts are provided at both ends of the two mounting blocks 18 and the two connecting blocks 17 to fix the connecting blocks 17 and the mounting blocks 18.

[0028] The mounting block 18 can be installed first in the appropriate position on the crane, and then the two connecting blocks 17 can be inserted into the mounting block 18 (e.g., Figure 1 and Figure 2 As shown in the figure, the connecting block 17 and the mounting block 18 are then fixed by tightening the bolts, thereby realizing the installation of the mounting strip 1.

[0029] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
