Description

Technical Field

[0001] This utility model relates to the field of lighting installation technology, and in particular to a tunnel lighting installation device. Background Technology

[0002] Tunnel lighting systems are crucial facilities for ensuring traffic safety and improving traffic efficiency. The stability of the lamp installation, the adjustability of its position, and the ease of subsequent maintenance are its main performance indicators. With the increasing standards of tunnel engineering construction, higher requirements are being placed on lamp installation technology.

[0003] Currently, tunnel lighting fixtures are mainly installed using welding and direct bolt fixing. While welding provides stability, it lacks flexibility and is difficult to adjust once installed. Bolt fixing, while simple, is difficult to adapt to the curved structure of tunnel walls and is also challenging to adjust. When maintenance is required on fixtures fixed inside the tunnel, the work vehicle needs to occupy a lane, which is extremely dangerous and prone to accidents in tunnels with high traffic volume and poor lighting. Therefore, a device is needed that allows maintenance personnel to move the lighting fixtures to a safe area for repair without closing lanes and disrupting traffic.

[0004] CN211694779U discloses a tunnel lighting fixture fixing device, which achieves sliding installation and spacing adjustment of the lighting fixture through a mounting plate, slide rail, and slider structure, and is equipped with a ventilation and cooling structure, which improves flexibility and heat dissipation performance to a certain extent. However, this device still has the following shortcomings: First, the slide rail is a linear structure, which is only suitable for installation along the tunnel direction and is difficult to adapt to the curved surface of the tunnel cross section; Second, positioning relies on limiting blocks, and the position of the limiting blocks is fixed, resulting in poor flexibility.

[0005] Therefore, there is a need for a device that can adapt to the curved surface structure of tunnels and adjust the installation position of lighting fixtures to address the shortcomings of existing technologies. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a tunnel lighting installation device that solves the problems of fixed installation positions, poor flexibility, and inconvenience in later maintenance associated with existing fixed lighting devices.

[0007] To solve the above problems, the technical solution adopted by this utility model is: a tunnel lighting installation device, including a base module and an adjustment component; the base module includes an arc-shaped fixing plate, the surface of the arc-shaped fixing plate in the length direction is provided with an arc-shaped guide groove, the cross-section of the arc-shaped guide groove is a T-shaped structure, and the inner wall of the arc-shaped guide groove is provided with a plurality of positioning recesses; the adjustment component includes a slider base and a locking mechanism, the slider base is an I-shaped structure, the lower part of the upper flange of the I-shaped slider base is provided with a positioning component that matches the positioning recesses of the arc-shaped guide groove, the locking mechanism is set on the side of the lower flange of the I-shaped slider base, the locking mechanism includes an eccentric wheel, a handle, and a pin, the eccentric wheel is rotatably connected to the slider base through the pin, and the handle is fixed on the eccentric wheel.

[0008] Compared with existing technologies, the beneficial effects of this solution are: 1. The slider base of this solution can slide along the arc-shaped guide groove, which facilitates the adjustment of the lamp position or the addition of lamps in the later stage, making maintenance and expansion more convenient and flexible; 2. This solution adopts an arc-shaped fixing plate, which is more suitable for the arc-shaped structure of tunnels.

[0009] Furthermore, the surface of the arc-shaped fixing plate along its length direction is provided with at least two arc-shaped guide grooves.

[0010] Furthermore, the slider base also includes a storage groove located inside the slider base, with a depth greater than the thickness of the friction plate.

[0011] Furthermore, the locking mechanism also includes a return spring, and the force plate and the slider base are connected by the return spring.

[0012] Furthermore, the positioning component is a ball bearing.

[0013] Furthermore, the positioning component is a resilient pin.

Detailed Implementation

[0021] The following detailed description illustrates the specific implementation method:

[0022] Example 1

[0023] The tunnel lighting installation device provided in this application includes a base module 1 and an adjustment component 2. The base module 1 is disposed on the tunnel wall, and the adjustment component 2 can slide and be positioned on the base module 1. The tunnel lighting fixture is installed on the adjustment component 2, thereby achieving the effect of convenient installation of the tunnel lighting fixture, adjustable position after installation, and high flexibility.

[0024] Specifically, the base module 1 includes an arc-shaped fixing plate 11. The arc-shaped fixing plate 11 is curved along its length to match the curvature of the tunnel wall, thus better fitting the tunnel wall. The arc-shaped fixing plate 11 has several bolt holes 12, which can be used to fix it to the tunnel wall with expansion bolts. At least two arc-shaped guide grooves 13 are provided on the surface of the arc-shaped fixing plate 11 along its length. The cross-section of the arc-shaped guide grooves 13 is a T-shaped structure. This T-shaped structure design allows the adjustment component 2 to better fit with the guide grooves, preventing the adjustment component 2 from coming out of the guide grooves. The arc-shaped guide grooves 13 are directly milled onto the surface of the fixing plate using a CNC milling machine. The inner wall of the arc-shaped guide grooves 13 has several positioning recesses 131, which are evenly distributed along the extension direction of the arc-shaped guide grooves 13, facilitating accurate positioning of the adjustment component 2. Because the tunnel wall is long, if the arc-shaped fixing plate is not segmented, the positioning recess 131 in the arc-shaped guide groove 13 is difficult to process; therefore, multiple arc-shaped fixing plates 11 are spliced ​​and fixed on the tunnel wall to form an arc-shaped fixing plate 11 set along the tunnel circumference, and the positioning recess 131 is processed in segments to reduce the processing difficulty.

[0025] Specifically, the adjustment component 2 includes a slider base 21 and a locking mechanism 22. The slider base 21 has an I-shaped structure and slides in conjunction with the arc-shaped guide groove 13. A positioning component 211, matching the positioning recess 131 of the arc-shaped guide groove 13, is provided on the lower part of the upper flange of the I-shaped slider base 21. The positioning component 211 is a compressible ball embedded in the upper flange of the slider base 21. When the compressible ball engages with the positioning recess 131, it generates tactile feedback, assisting the operator in positioning the slider base 21. The locking mechanism 22 is located on the lower flange side of the I-shaped slider base 21 and is used to fix the slider base 21 at a preset position in the arc-shaped guide groove 13. The locking mechanism 22 includes an eccentric wheel 221, a handle 222, and a pin 223. The eccentric wheel 221 is rotatably connected to the slider base 21 through the pin 223. The handle 222 is fixedly connected to the eccentric wheel 221. When the handle 222 is rotated to make the eccentric wheel 221 press down on the force plate 32, the force plate 32 transmits the force to the friction plate 31 through the connecting rod 34. The friction plate 31 presses against the arc-shaped guide groove 13 to fix the adjustment component 2.

[0026] The locking mechanism 22 also includes a return spring 33. The force plate 32 and the slider base 21 are connected by the return spring 33. When the force plate 32 is not under force, under the elastic force of the return spring 33, the force plate 32 moves away from the slider base 21, causing the connecting rod 34 to move away from the slider base 21, thereby causing the friction plate 31 to fall into the receiving groove 35 of the slider base 21. The receiving groove 35 is located inside the slider base 21 and its depth is greater than the thickness of the friction plate 31, which can completely accommodate the friction plate 31. The friction plate 31 is made of materials such as nylon, which has good friction performance and wear resistance.

[0027] The implementation principle of this embodiment is as follows: This tunnel lighting installation device fixes the arc-shaped fixing plate 11 of the base module 1 to the tunnel wall. The arc-shaped guide groove 13 provides a sliding track for the adjustment component 2. The slider base 21 of the adjustment component 2 slides within the arc-shaped guide groove 13, achieving positioning through the cooperation of compressible balls and positioning recesses 131. Operators can quickly determine the position through tactile feedback. The eccentric wheel 221 of the locking mechanism 22 then uses a clamping device to firmly fix the slider base 21 in the preset position of the arc-shaped guide groove 13, ensuring the stability of the lighting installation. After the lighting installation is completed, the locking mechanism 22 can be loosened, allowing the lighting and slider base 21 to slide together within the arc-shaped guide groove 13, thereby adjusting the lighting position. During later maintenance, the adjustment component 2 can be slid onto the side walls of the tunnel via the arc-shaped guide groove 13, allowing construction personnel to replace the lighting on the sidewalk, thus reducing the time spent occupying the lanes and lowering the risk of accidents.

[0028] Example 2

[0029] The difference between this embodiment and the previous embodiment is that the positioning component 211 of the adjustment assembly 2 uses an elastic pin. The elastic pin is installed on the lower part of the upper flange of the I-shaped slider base 21. When the slider base 21 slides in the arc-shaped guide groove 13, the elastic pin can be engaged in the positioning recess 131, thus achieving the positioning function. When the elastic pin is engaged in the positioning recess 131, a certain change in resistance will occur, and the operator can also perceive the determination of the position.

[0030] The implementation principle of this embodiment is as follows: using an elastic pin as the positioning component 211, the adjusting component 2 can also be accurately positioned within the arc-shaped guide groove 13. Compared with the compressible ball positioning method, the elastic pin structure is relatively simple, has a lower cost, and has a certain degree of elasticity, which can accommodate certain installation errors.

[0031] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
