Description

Technical Field

[0001] This utility model belongs to the field of airport lighting fixtures, specifically an extraction tool for the pre-embedded ring of the filling groove of an airport embedded deep barrel light. Background Technology

[0002] Recessed deep-recessed lights are widely used in all aspects of daily life and production, especially in large airports. Due to the special nature of airports, recessed deep-recessed lights are installed on the finished surfaces of the apron, taxiways, and shoulders. Since recessed deep-recessed lights provide navigational aids, they are an indispensable condition for the normal operation of an airport. During installation, to meet the airport's usage requirements, a ring-shaped groove needs to be created between the outer wall of the light fixture's barrel and the pavement concrete. This groove is then filled with a cushioning material approximately 2 cm wide and 2.5 cm deep. The traditional method involves directly cutting the pavement concrete into annular grooves using machinery after pouring. This method is labor-intensive, inefficient, has high labor costs, and produces poor-quality annular grooves. To avoid these drawbacks, a new method has emerged where pre-embedded rings are used during the pavement concrete pouring process to create the annular grooves. The specific steps are as follows: First, a pre-embedded ring is made to meet the size requirements of the annular groove. Next, the pre-embedded ring is fitted onto the top of the recessed deep-tube light fixture at the airport, and the light fixture is fixed in its installation position. Then, the pavement concrete is poured. Finally, the pre-embedded ring is removed from the top of the light fixture's tube, and the annular groove is formed at the original installation position of the pre-embedded ring.

[0003] Currently, when removing the embedded ring from the top of the lamp holder, there are no special tools available. Instead, a pull rod is directly threaded onto the threaded hole of the embedded ring, and then the pull rod is pulled vertically to remove the embedded ring from the lamp holder; alternatively, the embedded ring is pried off mechanically. During the process, it has been observed that cracks appear in the concrete wall of the annular groove after the embedded ring is removed, and even damage occurs at the groove opening. Utility Model Content

[0004] The purpose of this invention is to provide a tool for extracting the pre-embedded ring of the filling groove of an airport embedded deep barrel light, which is used to remove the pre-embedded ring and improve the quality of the annular groove.

[0005] The technical solution adopted in this utility model is as follows: an extraction tool for the pre-embedded ring of the filling groove of an airport embedded deep barrel light, wherein several threaded holes are evenly distributed along the circumference of the pre-embedded ring; the pre-embedded ring is fitted onto the outer periphery of the top of the light fixture and pre-embedded in the concrete pavement; including a screw rod, a fixing seat is threadedly connected to the screw rod, and several chains are evenly distributed around the outer periphery of the fixing seat, one end of each chain is connected to the fixing seat, and the other end is connected to a bolt; the bolt is threadedly connected to the threaded holes on the pre-embedded ring; a support foot cup is provided at the bottom end of the screw rod for supporting the center of the top surface of the light fixture; the bottom end of the screw rod and the bottom of the support foot cup are rotatably connected about the screw rod axis.

[0006] Furthermore, the bottom surface of the support foot cup is a plane adapted to the top surface of the lamp.

[0007] Furthermore, a handle is provided at the top of the screw.

[0008] Furthermore, the handle consists of two gripping rods, one end of which is fixed to the top of the screw, and the other end extends radially outward along the screw and tilts upward along the screw axis; and the two gripping rods are arranged symmetrically about the screw.

[0009] Furthermore, a soft, non-slip layer is provided on the outer periphery of the grip bar of the handle.

[0010] Furthermore, the bottom end of the screw is provided with a connector, which includes a spherical head and a shaft portion that fixes the spherical head to the bottom end of the screw; the support foot cup includes a base at the bottom and a top seat at the top; the base is provided with a hemispherical concave cavity that is recessed inward on its top surface and fits the spherical head of the connector; the top seat is provided with a hemispherical concave cavity that is recessed inward on its bottom surface and fits the spherical head of the connector, and is provided with a through hole that extends vertically through the upper concave cavity to the top seat, the through hole fitting the shaft portion of the connector; the top seat has a split structure; the top seat and the base are connected by screws.

[0011] Furthermore, the fixing base includes a circular base body with several ear seats distributed around its outer perimeter. Each ear seat has a connecting hole, and the chain is connected to the connecting hole.

[0012] Furthermore, the bolt includes a connecting ring at the top for connection with the chain and a threaded rod at the bottom for connection with a threaded hole on the pre-embedded ring, the connecting ring being fixed to the top of the threaded rod.

[0013] Furthermore, there are three threaded holes on the pre-embedded ring and three chains.

[0014] The beneficial effects of this utility model are as follows: This utility model uses a support foot cup placed at the center of the lamp cover of an embedded deep-barrel lamp. Rotating the screw causes the fixing seat to move upwards, driving the chain to exert an upward pulling force on the pre-embedded ring of the filler material, thus removing the pre-embedded ring. Because vertical force is used during the removal process, the risk of damage to the lamp box and concrete caused by mechanical prying is avoided. The rotation and pulling via the screw and chain result in better quality of the annular groove after the pre-embedded ring is removed. When using this tool, the support foot cup is placed against the top cover of the lamp, and the bolt is installed into the threaded hole of the pre-embedded ring. Installation is convenient, and pulling by rotating the screw saves effort. The ease of installation and disassembly, combined with labor-saving operation, improves work efficiency and provides better construction conditions for subsequent filling of buffer materials, thus well meeting the requirements of airport operations.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] In this specification, the terms "vertical," "upper," "vertical," "horizontal," "top," and "bottom," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientation or positional relationship shown is for the purpose of describing the present invention only, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0026] Airport recessed deep-recessed lights have their bulbs embedded in the pavement through concrete pouring. To meet airport usage requirements, a ring-shaped groove needs to be created between the outer wall of the bulb and the pavement concrete during installation. This groove is filled with a buffer material approximately 2 cm wide and 2.5 cm deep. To avoid the drawbacks of directly cutting the groove mechanically, a method of pre-embedding a ring during pavement concrete pouring has been developed to create the groove. The specific steps are as follows: First, a pre-embedding ring is fabricated to meet the dimensions of the ring groove. Next, the pre-embedding ring is fitted onto the top of the bulb of the airport recessed deep-recessed light, and the bulb is fixed in its installation position. Then, the pavement concrete is poured. Finally, the pre-embedding ring is removed from the top of the bulb, forming the ring groove in its original installation location.

[0027] Currently, when removing the embedded ring from the top of the lamp holder, there are no specialized tools available. Instead, a screw or similar tool adapted to the threaded hole 601 of the embedded ring 6 is temporarily used as a pull-out rod. The pull-out rod is installed on the corresponding threaded hole 601 of the embedded ring 6, and then a jack is attached to the end of the pull-out rod. The embedded ring is then lifted vertically using the jack, or it can be pried up directly. During the operation, it was found that cracks appeared in the concrete wall of the annular groove after the embedded ring was removed, and even damage occurred at the groove opening.

[0028] To avoid the drawbacks of disassembling the pre-embedded ring mentioned above, this utility model discloses a tool for extracting the pre-embedded ring from the filling groove of an airport embedded deep barrel light, such as... Figure 1-8 As shown, the device includes a screw 2, a fixed seat 3 threadedly connected to the screw 2, and several chains 4 evenly distributed around the outer periphery of the fixed seat 3. One end of each chain 4 is connected to the fixed seat 3, and the other end is connected to a bolt 8. The bolt 8 is threadedly connected to the threaded hole 601 on the pre-embedded ring 6. The bottom end of the screw 2 is provided with a support foot cup 5 for supporting the center of the top surface of the lamp 7. The bottom end of the screw 2 and the bottom of the support foot cup 5 are rotatably connected about the axis of the screw 2.

[0029] In use, the support foot cup 5 is placed in the center of the lamp cover of the lamp fixture 7. Rotating the screw 2 drives the fixing seat 3 and chain 4 to move upward, removing the embedded ring 6 from the lamp barrel of the lamp fixture 7. This avoids the risk of damaging the lamp barrel and pavement concrete caused by directly prying up the embedded ring 6 manually, and ensures that the size and appearance quality of the annular groove meet the requirements after the embedded ring 6 is removed.

[0030] Several chains 4 are evenly distributed around the outer perimeter of the fixed base 3. It is required that not only the installation points of the chains 4 on the fixed base 3 are evenly distributed around the outer perimeter of the fixed base 3, but also that the connection points of the chains 4 on the embedded ring 6 are evenly distributed around the ring 6. In this way, it is ensured that the embedded ring 6 is symmetrically stressed, which is conducive to eliminating stress concentration and protecting the structure of the annular groove.

[0031] During the pulling process, by rotating the screw 2, the fixed seat 3 moves vertically as it rotates relative to the screw 2. Compared with direct pulling, this is more effective in protecting the groove wall of the annular groove from damage due to pulling. Moreover, vertical movement during rotation is also less strenuous.

[0032] A tripod can be used as the support foot cup 5. In this embodiment, the bottom surface of the support foot cup 5 is a plane that fits the top surface of the lamp 7. With the same floor area (the usable area of ​​the top surface of the lamp 7), the bottom surface of the planar support foot cup 5 completely fits the top surface of the lamp 7. Compared with the contact area between the tripod and the top surface of the lamp 7, its contact area is larger, and the risk of damaging the top surface of the lamp 7 is greatly reduced.

[0033] A handle 1 is provided at the top of the screw 2. The handle 1 is designed to allow the operator to hold the handle 1 and rotate the screw 2.

[0034] Specifically, the handle 1 consists of two gripping rods. One end of the gripping rod is fixed to the top of the screw 2, and the other end extends radially outward along the screw 2 and tilts upward along the screw 2 axis. The two gripping rods are arranged symmetrically about the screw 2.

[0035] To improve grip comfort and prevent slippage, the outer periphery of the grip bar of handle 1 is provided with a soft anti-slip layer.

[0036] Preferred, such as Figure 6 and Figure 7 As shown, the bottom end of the screw 2 is provided with a connector 201, which includes a spherical head and a shaft portion that fixes the head to the bottom end of the screw 2. The axis of the shaft portion passes through the center of the head. The support foot cup 5 includes a base 501 at the bottom and a top seat 502 at the top. The base 501 has a hemispherical recessed cavity 503 that is recessed inward from its top surface and fits the head of the connector 201. The top seat 502 has a hemispherical upper recessed cavity 504 that is recessed inward from its bottom surface and fits the head of the connector 201. A through hole is provided in the upper recessed cavity 504 that vertically penetrates the top seat 502. The through hole fits the shaft portion of the connector 201. The top seat 502 has a split structure, that is, the top seat 502 is detachably assembled from two identical splicing blocks. The top seat 502 and the base 501 are connected by screws. In this configuration, the spherical cavity formed by the top seat 502 and the base 501 is used for the spherical connector 201 to rotate inside. The top seat 502 has a split structure, and the through hole is adapted to the shaft of the connector 201, so that the top seat 502 surrounds the shaft of the connector 201. The shaft of the connector 201 is a round shaft, which limits the rotation direction of the connector 201 in the spherical cavity, so that it can only rotate around the axis of the screw 2, thereby ensuring the balance of force on each chain.

[0037] The base 501 can be cylindrical, triangular prism, or similar shapes. In this embodiment, the base 501 is a frustum shape, wider at the bottom and narrower at the top. The wider bottom of the frustum-shaped base 501 results in a large contact area and good support stability; the narrower top saves on manufacturing materials and reduces weight.

[0038] The mounting base 3 can be directly set to a circle, and the connection hole for installing the chain can be set perpendicular to the mounting base 3, or as follows: Figure 5 As shown, the fixing base 3 includes a circular base body 301, and several ear seats 302 are distributed around the outer periphery of the base body 301. The ear seats 302 are provided with connecting holes 303, and the chain 4 is connected to the connecting holes 303.

[0039] To facilitate connection with chain 4, such as Figure 8 As shown, the bolt 8 includes a connecting ring 801 at the top for connecting with the chain 4 and a threaded rod 802 at the bottom for connecting with the threaded hole 601 on the pre-embedded ring 6. The connecting ring 801 is fixed to the top of the threaded rod 802. The annular lock at the bottom of the chain 4 is detachably connected to the connecting ring 801.

[0040] There are three threaded holes 601 on the pre-embedded ring 6, and three chains 4.
