Detailed Description

The first embodiment.

The embodiment provides an illumination scheme integrated on a portal crane body 1 (hereinafter referred to as a portal crane), which is realized by an illumination assembly, and needs to be modified on civil structures such as an elevated bridge 2 to adapt to the illumination assembly.

The principle of the use method of the lighting assembly is as follows:

1. starting the longitudinal lifting mechanism 4 to drive the telescopic arm 6 to descend to a proper height;

2. starting the swing motor 5 to drive the telescopic arm 6 to swing and expand, and stopping the swing motor 5 when the telescopic arm 6 points to the direction of the gap 93 of the overhead bridge 2;

3. starting the telescopic mechanism 7 to drive the telescopic arm 6 to extend out, and stopping the telescopic mechanism 7 after the LED lamp 8 completely extends into the notch 93;

4. turning on the LED lamp 8, rotating the lamp rotating disc 13 to drive the LED lamp 8 to rotate to a proper illumination angle and then stop rotating;

5. when recovering and storing, the steps 4 to 1 are operated in reverse.

In this embodiment, the longitudinal lifting mechanism 4 is installed on the support frame of the gantry crane, and may be implemented by any feasible scheme, such as an electric slide rail, a hydraulic lifting mechanism, etc., taking the electric slide rail as an example, the telescopic arm 6 and the swing motor 5 are both arranged on a slide block of the electric slide rail, the telescopic arm 6 may be separately hinged with the slide block, and the swing motor 5 is dynamically connected with the telescopic arm 6 through a transmission mechanism. The telescopic arm 6 adopts a conventional structure, can adopt a traditional mechanism with a plurality of stages of sleeves mutually sleeved, and can also adopt other feasible structures. The lamp rotating disc 13 is detachably connected with the telescopic arm 6, and meanwhile, the lamp rotating disc and the telescopic arm are also hinged in a manner of rotating shaft screws and the like, so that a limiting means can be correspondingly provided, the uncontrolled swinging of the LED lamp 8 can be limited in the lifting, stretching and other stages, the limiting means is not limited, for example, a common limiting means for limiting the rotation can be adopted, and even a binding belt and the like can be adopted. The telescopic mechanism 7 can also adopt a mature existing scheme, such as a hydraulic mechanism or a linear motor, in particular a linear motor, and can adopt a linear motor product with a telescopic stroke of 1000mm to 1800mm according to the construction site space.

The present embodiment shows a modified scheme of the elevated bridge 2, wherein notches 93 are formed on two sides of the elevated bridge 2 for the LED lamp 8 to extend into, and the trench can be formed on the top of two sides of the trench wall to form a trench inclined towards the inside of the trench, so that the LED lamp 8 passes through the gap between the chassis of the vehicle from the oblique upper side to extend into the trench.

The installation bases 14 on the lamp rotating disc 13 can be multiple as required, the array is arranged on the lamp rotating disc 13, one LED lamp 8 is installed on each installation base 14, the structure of the installation base 14 is not limited, the installation mode of the installation base 14 and the LED lamp 8 can be in threaded connection, and other detachable connection modes can also be adopted. The LED lamp 8 may employ a charging product.

In the embodiment, the telescopic arm 6 is divided into a three-section structure, the rear arm 10 is a support frame structure which can be adapted to a gantry crane, a C-shaped mechanism can be arranged, the structure can clamp the support frame in a manner similar to clamping, and the support frame is also provided with a longitudinal lifting mechanism 4, so that the longitudinal lifting mechanism 4 is also clamped in practice. However, there is no direct contact between the rear arm 10 and the support frame, so that the rear arm 10 is clamped between the support frames only with a tendency to move. In order to simplify the structure, the rear arm 10 may be in contact with the support frame when sliding, and the effect of the rear arm 10 is not affected, but it is preferable to provide a roller for reducing friction on the rear arm 10. The swing motor 5 is the same as the long-team motor, and is only used for providing swing power for the telescopic arm 6, and the specific structure of the transmission mechanism of the swing motor 5 is not limited.

There is a preference in this embodiment that the front arm 12 of the telescopic arm 6 also employs the same mechanism as the rear arm 10, but the front arm 12 is much thinner than the rear arm 10 for the convenience of the drawing-in and drawing-out operation, and the front arm 12. The lamp rotating disc 13 rotates at the end part of the front arm 12, and can drive the LED lamp 8 to rotate and be accommodated in the front arm 12, so that collision in use is avoided as much as possible. The intermediate sleeve 11 is located between the front arm 12 and the rear arm 10, and is slidably fitted with the front arm 12 and fixedly connected with the rear arm 10.

Example two.

The embodiment provides more specific, the more convenient installation base 14 of use of structure, and it adopts the ball bearing to connect installation frame 16, and after installation LED lamp 8, can make LED lamp 8 realize 360 degrees rotations in ball bearing mechanism 15 swing range, can adapt to more the lighting requirements of crossing different directions.

The inner base 17 and the side brackets 19 of the mounting frame 16 are fixed, while the outer base 18 is structurally added to the inner base 17 with a clamping effect mechanism that can cooperate with the inner base 17 to clamp the LED lamp 8 on the mounting base 14. For example, when the outer base 18 is screwed to the side bracket 19 and the outer base 18 is fixed to the side bracket 19, the outer base 18 itself takes a clamping action on the LED lamp 8. The outer base 18 may also be clamped by other structures, for example, the outer base 18 can be connected to the outer base 18, and when the outer base 18 is used for mounting the LED lamp 8, the outer base 18 can be used for increasing the clamping effect of the outer base 18 on the LED lamp 8.

However, in the present embodiment, there are two independent modifications for the mechanism with clamping effect, the first modification is to make the clamping plate I rotatably clamping the LED lamp 8 more tightly clamped by using an elastic element on the basis of the hinge joint between the clamping plate I and the side bracket 19, and to drive the clamping plate to reset after the LED lamp 8 is disassembled, and the arrangement and specific structure of the elastic element can be realized by referring to the conventional use case of a torsion spring. The second modification is to design the splint II20 into a letter L shape, so that one end of the splint II can be sleeved with the side bracket 19 to slide, and the other end of the splint II realizes a clamping function; the mutually sleeved sliding can be that the clamping plate II20 is provided with a groove and the side bracket 19 is sleeved in the groove, the side bracket 19 can be provided with a groove and the clamping plate II20 is sleeved in the groove, the elastic element can be arranged between the clamping plate II20 and the side bracket 19, and when the clamping plate II20 slides, the elastic element applies elastic force (reacting force) to the clamping plate II20 to realize the clamping effect.

In this embodiment, in order to better mount the LED lamp 8 in the mounting frame 16, the inner base 17 is provided with a claw-shaped (claw-shaped) limiting structure to limit the LED lamp 8 like a claw, and the claw-shaped limiting structure 21 may be a limiting baffle plate that can be replaced if it functions as the claw-shaped structure.

Example three.

The embodiment provides an improved scheme for smooth work of the LED lamp 8, and specifically comprises the steps of completely hollowing out the middle of the outer base 18 to enable the inner side and the outer side of the outer base to be communicated, arranging through holes in corresponding positions on the cover plate 23 according to the positions of charging ports of the LED lamps 8 of different brands, covering the cover plate 23 on the hollowed-out portion 22, and enabling a power line to penetrate through the through holes. The hollow 22 is designed to be opened in both the clamping plate I and the clamping plate II, and fig. 8 illustrates the clamping plate II as an example only.
