Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to lighting equipment for highway tunnel construction. Background Art

[0002] During the tunnel construction process, lighting is very important. Some darker areas need to be supplemented with light to ensure the construction field of vision. There are two common lighting methods in the prior art. One is to use a movable lighting device that can be moved and adjusted at any time according to the construction progress. The other is to fix the lighting lamp on the inner wall of the already formed tunnel.

[0003] The existing lighting device is equipped with a long pole to meet the lighting range in the vertical direction. However, due to the uneven ground during tunnel construction, the lighting device cannot be well stabilized on the ground. In addition, the vibration generated by the operation of the construction equipment makes the lighting device easy to topple over, thus failing to meet the lighting needs. Utility Model Content

[0004] The utility model aims to provide a lighting device for highway tunnel construction, which has the advantages of being able to lower its own center of gravity, adapt to uneven terrain and not easily tip over, thereby solving the problem that the current lighting device is prone to tipping over when used in a construction tunnel.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A lighting device for highway tunnel construction, comprising an irradiation lamp, wherein a support mechanism is provided on the surface of the irradiation lamp;

[0006] The supporting mechanism includes a vertical pole, the irradiator is fixed on the top of the vertical pole, a connecting sleeve is fixed on the surface of the vertical pole, three combined shells are fixed on the surface of the connecting sleeve, a support rod is hinged on the surface of the combined shell, a sleeve is slidably connected to the surface of the vertical pole, a water tank is fixed to the bottom of the sleeve, a mounting shell is fixed on the surface of the support pole, a screw is threaded through the surface of the mounting shell, a ball joint is fixed at the bottom of the screw, a connecting shell is slidably connected to the surface of the ball joint, an airbag is fixed at the bottom of the connecting shell, and a friction pad is fixed at the bottom of the airbag.

[0014] The utility model provides a supporting mechanism so that the irradiation lamp can still obtain good stability on uneven roads. The vertical pole is used to support and install the irradiation lamp. After the support rod is rotated downward until the multiple support rods are fully unfolded, the bottom of the friction pad can contact the ground. When the ground in the tunnel is uneven, the rotating screw rod can adjust the height position of the friction pad at the bottom of one side of the support rod so that the surface of the friction pad can contact the ground. Thus, the device can find a balance point through the contact between the multiple friction pads and the ground, thereby maintaining the balance of the device. At the same time, the sleeve can drive the water tank to move downward so that the water tank can contact the ground. Water can be added inside the water tank to increase the overall weight of the device, lower the center of gravity of the device, improve stability, and make the device less likely to tip over. The connecting shell can slide on the surface of the ball joint, so that the friction pad can freely adjust the angle in multiple directions, so that it can better adapt to the complex tunnel construction environment and uneven surface. When the device is vibrated, the airbag can absorb and disperse energy through the compression and expansion of the internal gas, thereby reducing the impact force directly transmitted to the main body of the irradiator and its upright pole, protecting the equipment from damage. At the same time, the water tank can also use the flow characteristics of water to absorb part of the vibration energy, thereby maintaining the stability of the lighting.

DETAILED DESCRIPTION

[0020] See also Figure 1-4 , a lighting device for highway tunnel construction, comprising an irradiation lamp 1, a support mechanism 2 is arranged on the surface of the irradiation lamp 1;

[0021] The irradiation lamp 1 is used for lighting, and the supporting mechanism 2 enables the irradiation lamp 1 to have good stability on uneven roads.

[0022] The support mechanism 2 includes a vertical pole 201, the irradiation lamp 1 is fixed on the top of the vertical pole 201, a connecting sleeve 202 is fixed on the surface of the vertical pole 201, three combination shells 203 are fixed on the surface of the connecting sleeve 202, a support rod 204 is hinged on the surface of the combination shell 203, a sleeve 205 is slidably connected to the surface of the vertical pole 201, a water tank 206 is fixed to the bottom of the sleeve 205, a mounting shell 207 is fixed to the surface of the support rod 204, a screw 208 is threaded through the surface of the mounting shell 207, a ball joint 209 is fixed to the bottom of the screw 208, a connecting shell 210 is slidably connected to the surface of the ball joint 209, an air bag 211 is fixed to the bottom of the connecting shell 210, and a friction pad 216 is fixed to the bottom of the air bag 211;

[0023] The vertical pole 201 is used to support and install the irradiation lamp 1. After the support rod 204 is rotated downward until the multiple support rods 204 are fully unfolded, the bottom of the friction pad 216 can contact the ground. When the ground in the tunnel is uneven, the rotating screw 208 can adjust the height position of the friction pad 216 at the bottom of one side of the support rod 204 so that the surface of the friction pad 216 can contact the ground. Thus, through the contact between the multiple friction pads 216 and the ground, the device can find a balance point to keep the device balanced. At the same time, the sleeve 205 can drive the water tank 206 to move downward so that the water tank 206 can contact the ground, and water can be added to the water tank 206. , thereby increasing the overall weight of the device, lowering the center of gravity of the device, improving stability, and making the device less likely to tip over. The connecting shell 210 can slide on the surface of the ball joint 209, so that the friction pad 216 can freely adjust the angle in multiple directions, so that it can better adapt to the complex tunnel construction environment and uneven surface. When the device is vibrated, the airbag 211 can absorb and disperse energy through the compression and expansion of the internal gas, thereby reducing the impact force directly transmitted to the main body of the irradiator 1 and its upright pole 201, protecting the equipment from damage. At the same time, the water tank 206 can also use the flow characteristics of water to absorb part of the vibration energy, thereby maintaining the stability of the lighting.

[0024] Furthermore, a slide groove 217 is provided on the surface of the combined shell 203, a positioning bolt 218 is fixed on the surface of the support rod 204, the positioning bolt 218 is slidably connected to the surface of the slide groove 217, and a fastening nut 219 is threadedly connected to the surface of the positioning bolt 218;

[0025] The support rod 204 can rotate on the surface of the combined shell 203, and the positioning bolt 218 can slide on the surface of the slide groove 217. Rotating the positioning bolt 218 can limit the support rod 204, so that the support rod 204 can be folded upward, thereby reducing the space occupied by the device during transportation.

[0026] Furthermore, a first knob 212 is threadedly penetrated through the surface of the sleeve 205;

[0027] After the sleeve 205 is adjusted to be located on the surface of the upright pole 201 , the first knob 212 can be rotated to obtain a limiting effect on the sleeve 205 .

[0028] Furthermore, a second knob 213 is threadedly passed through the surface of the connection shell 210, and a clamping pad 214 is fixed to one end of the second knob 213;

[0029] After the connection shell 210 is adjusted to be located on the surface of the ball joint 209 , the second knob 213 can be rotated to move the clamping pad 214 toward the surface of the ball joint 209 , so that the clamping pad 214 can be squeezed and deformed, thereby limiting the connection shell 210 .

[0030] Furthermore, the interior of the installation shell 207 is filled with water, and a partition 215 is fixed to the inner wall of the installation shell 207;

[0031] Filling the interior of the mounting shell 207 with water can increase the overall weight of the mounting shell 207, while the provision of the partition 215 prevents the water flow from directly contacting the screw 208, thereby preventing the water flow from leaking through the threaded connection.

[0032] Furthermore, the connecting sleeve 202, the friction pad 216 and the clamping pad 214 are all made of rubber;

[0033] The rubber connecting sleeve 202 can fully absorb the vibration transmitted from the support rod 204 and the combined shell 203 to the vertical pole 201, thereby reducing the vibration effect on the irradiation lamp 1. The rubber friction pad 216 has a vibration absorption function and also has good friction, thereby improving the stability of the device. The clamping pad 214 made of rubber can increase the limiting effect on the connecting shell 210.

[0034] Further, the fastening nut 219 is a butterfly nut;

[0035] The fastening nut 219 is a butterfly nut, so that the operator can rotate the fastening nut 219 without the aid of tools.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
