Description

Technical Field

[0001] The present invention relates to the technical field of traffic engineering, and specifically to an omnidirectional searchlight that can be used by traffic engineering construction units. Background Art

[0002] In existing traffic engineering construction, due to the construction period, overtime construction is often carried out at night. However, because the construction scope of traffic engineering construction is very large, it is often necessary to erect multiple searchlights for illumination, resulting in huge energy consumption and easy waste. Moreover, existing searchlights are fixed on lamp posts and cannot arbitrarily change the illumination range of the searchlights.

[0003] An omnidirectional searchlight that can be used by traffic engineering construction units, according to the patent with publication number CN205640465U, includes a base. The top of the base is movably connected with a movable block. The bottom of the inner cavity of the base is fixedly installed with a driving device, and the top of the driving device is fixedly connected with the bottom of the movable block through a connecting block. Both sides of the bottom of the base are fixedly installed with moving devices. One side of the connecting block away from the base is fixedly connected with a lamp post. One end of the lamp post away from the connecting block is communicated with a round lamp through a partition, and a movable lamp is sleeved on the lamp post. A square lamp is fixedly installed on the surface of the movable lamp. A through rod penetrating the lamp post is fixedly installed in the movable lamp. One end of the through rod located in the inner cavity of the lamp post is sleeved with a through rod sleeve, and the bottom of the through rod sleeve is fixedly connected with a movable rod.

[0004] For the above related solutions, the horizontal movement of the round lamp and the square lamp is realized through the cooperation of a servo motor and a lead screw, and the lifting of the square lamp is realized through the cooperation of a driving motor, a transmission belt, a connecting rod, etc. Although this structure can change the illumination range of the searchlight within a small range, it cannot synchronously realize the stable support of the searchlight, resulting in insufficient anti-overturning ability and anti-displacement ability, so that the stability of the searchlight during use is relatively low. At the same time, the change of the illumination range is limited, and multi-directional synchronous adjustment cannot be realized. Summary of the Invention

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 - 5 , the present invention provides a technical solution: an omnidirectional searchlight that can be used by traffic engineering construction units, including a moving base 1. The moving base 1 includes rollers for moving the device, and the moving base 1 is used to support and move the column 4. A moving column 4 is fixed at the center position of the moving base 1. One end of the column 4 is movably connected to a liftable support cylinder 5 inside, and a main lamp 2 for illuminating the construction is installed at the top of the support cylinder 5;

[0034] In Figures 1 - 3 and Figure 7 , Figure 8 : A servo motor 9 for driving the rotating shaft 10 to rotate forward and backward is installed inside the moving base 1, and the output end of the servo motor 9 is connected to the rotating shaft 10 through a coupling.

[0035] Specifically, when the servo motor 9 works, the output end of the servo motor 9 drives the rotating shaft 10 to rotate forward or backward.

[0036] In Figure 3 , Figure 7 andFigure 8 In the middle: A lifting mechanism 6 for driving the lifting of the support cylinder 5 is provided at the top of the rotating shaft 10. The lifting mechanism 6 includes a displacement sleeve A603 movably sleeved outside the rotating shaft 10 and a circular plate 605 welded to the surface of the rotating shaft 10. A guiding block A602 is arranged inside the displacement sleeve A603, and a guiding groove A601 which forms a sliding structure with the guiding block A602 is provided on the surface of the rotating shaft 10.

[0037] Specifically, since the displacement sleeve A603 and the rotating shaft 10 are slidably connected through the guiding groove A601 and the guiding block, the displacement sleeve A603 and the support cylinder 5 can perform rapid lifting and lowering in the vertical direction. When the servo motor 9 rotates forward, the displacement sleeve A603 drives the support cylinder 5 to move upward, so that the main lamp 2 quickly rises to the highest point, and the lighting range is expanded. When rotating in the reverse direction, it quickly descends to the storage height, reducing the overall space occupation.

[0038] In Figure 3 、 Figure 7 and Figure 8 In the middle: The guiding groove A601 includes a groove for the lifting of the displacement sleeve A603 by rotating around the lifting mechanism 6, and annular grooves at both upper and lower ends of the groove.

[0039] Specifically, since the guiding groove A601 is composed of a groove and annular grooves symmetrically arranged at both ends of the groove, when the displacement sleeve A603 moves to a specified position and the rotating shaft 10 continues to rotate, the guiding block A602 can slide in the annular groove, so that the displacement sleeve A603 will not hinder the continuous rotation of the rotating shaft 10.

[0040] In Figure 3 、 Figure 7 and Figure 8 In the middle: Support springs 604 are connected to one ends of the two circular plates 605 close to each other.

[0041] Specifically, when the guiding block A602 is located in the annular groove, the displacement sleeve A603 presses the support spring 604. When it is necessary to move the displacement sleeve A603 upward or downward, the support spring 604 provides an elastic force to the displacement sleeve A603, so that the guiding block A602 inside the displacement sleeve A603 can smoothly enter the groove.

[0042] In Figure 3 、 Figure 7 and Figure 8 In the middle: Limiting blocks 12 for preventing the displacement sleeve A603 from rotating are provided on both sides of the displacement sleeve A603. The limiting blocks 12 are embedded in anti-deviation grooves 13 opened on the inner wall of the column 4, so that the displacement sleeve A603 will not rotate during the up and down movement in the column 4.

[0043] Specifically, through the cooperation of the limit block 12 and the anti-deviation groove 13, the displacement sleeve A603 can be supported and limited to prevent the displacement sleeve A603 from rotating self, so that the displacement sleeve A603 only moves in the vertical direction during the rotation of the rotating shaft 10.

[0044] In Figures 1 - 3 and Figures 6 - 8 : A stretching mechanism 7 penetrating the column 4 is arranged below the displacement sleeve A603 on the outer side of the rotating shaft 10. The stretching mechanism 7 includes a displacement sleeve B703 movably sleeved on the rotating shaft 10 and a displacement frame 704 movably sleeved on the column 4. A guide block B702 is welded to one side of the displacement sleeve B703 close to the rotating shaft 10. A guide groove B701 which forms a sliding structure with the guide block B702 is arranged below the guide groove A601 on the surface of the rotating shaft 10, and the guide groove B701 is arranged in a spiral structure.

[0045] Specifically, since the displacement sleeve B703 and the rotating shaft 10 are slidably connected through the guide groove B701 and the guide block B702, the displacement sleeve B703 and the displacement frame 704 move in the vertical direction. When the servo motor 9 rotates forward, the displacement sleeve B703 and the displacement frame 704 move vertically upward, and the lighting range is expanded. When rotating in the reverse direction, the displacement sleeve B703 and the displacement frame 704 move vertically downward to reset the side lamp 3 and reduce the overall space occupation.

[0046] In Figures 1 - 8 : The displacement frame 704 includes an annular plate and connecting columns welded to the inner side of the annular plate at equal angles. One side of the connecting column far from the annular plate is welded to the displacement sleeve B703. The top end of the displacement frame 704 is rotatably provided with support rods 705 for installing the side lamp 3 at equal angles through hinge seats, and a side lamp 3 for illuminating the construction is installed at one end of the support rod 705 far from the displacement frame 704. Side plates 707 are welded to the surface of the column 4 at equal angles. A limit groove A708 for supporting and guiding the limit member A706 is arranged inside the side plate 707. A limit member A706 which forms a sliding structure with the limit groove A708 is welded to one side of the support rod 705 close to the side plate 707.

[0047] Specifically, since the support rod 705 is hinged to the displacement frame 704 through a hinge seat and is slidably connected to the side plate 707 through the limit groove A708 and the limit member A706, the support rod 705 drives the side lamp 3 to deflect around the hinge seat as the axis, so that the four side lamps 3 are synchronously radially unfolded, cooperating with the main lamp 2 to form vertical and horizontal two-way lighting coverage, effectively avoiding the problem of dark areas around the traditional searchlight due to concentrated light sources, and being able to adjust the unfolding range according to actual usage requirements, improving adaptability. Also, when not in use, it can be retracted to greatly reduce the space occupied, facilitating vehicle transportation and warehouse management. In addition, the linkage design of the displacement sleeve A603, the displacement sleeve B703 and the rotating shaft 10 realizes single rotating shaft 10 control, reducing energy consumption compared with traditional multi-motor drive.

[0048] In Figure 1 and Figures 3 - 6 : The limit groove A708 includes a long inclined groove and a longitudinal groove located at the bottom end of the long inclined groove, and one side of the long inclined groove away from the longitudinal groove is communicated with the transverse groove.

[0049] Specifically, during the process of the main lamp 2 rising to the highest point, the limit member A706 moves up synchronously but always remains in the longitudinal groove. During this process, the support rod 705 will not deflect in angle. Therefore, the rise of the main lamp 2 will not affect the angular deflection of the support rod 705. During the process of the limit member A706 moving from the longitudinal groove into the long inclined groove and then continuing to move into the transverse groove, the support rod 705 can be made to gradually deflect around the hinge seat as the axis.

[0050] In Figures 2 - 4 : The surface of the column 4 is provided with a chute 11 that forms a sliding structure with the displacement frame 704 at equal angles below the side plate 707.

[0051] Specifically, the chute 11 can play a role in supporting and guiding the displacement frame 704, so that the displacement frame 704 only moves in the vertical direction when the rotating shaft 10 rotates, improving the stability of the displacement frame 704 during the moving process.

[0052] In Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 9 and Figure 10In the middle: A support mechanism 8 is provided between the moving base 1 and the displacement frame 704. The support mechanism 8 includes vertical plates 801 welded at equal angles to the bottom end of the displacement frame 704 and support plates 807 welded at equal angles to the top end of the moving base 1. The support plates 807 are used to stably support the support legs 804 in cooperation with the support shafts 806. One end of the vertical plate 801 away from the displacement frame 704 is rotatably connected to a limiting member B803 to cooperate with the limiting groove B805 to flip the support legs 804. Symmetrically arranged support shafts 806 are rotatably connected to the inner side of the support plates 807. A support leg 804 is welded between the two support shafts 806. A limiting groove B805 which forms a sliding structure with the limiting member B803 is provided at one end of the support leg 804 close to the vertical plate 801. An anti-slip plate 802 is welded to the end of the support leg 804 away from the vertical plate 801. The anti-slip plates 802 arranged at equal angles can play a role in dispersing pressure and improving the placement stability of the moving base 1.

[0053] Specifically, when the displacement frame 704 moves vertically upward, it synchronously drives the vertical plate 801 to move vertically upward. Since the support leg 804 is rotatably connected to the support plate 807 through the support shaft 806, and the vertical plate 801 is slidably connected to the support leg 804 through the limiting groove B805 and the limiting member B803, and the limiting groove B805 is composed of a short inclined groove and a straight groove, during the process that the limiting member B803 moves from the short inclined groove into the straight groove, the support leg 804 makes a rapid flip with the support shaft 806 as the axis, and the anti-slip plate 802 is in close contact with the ground, thereby expanding the support area, greatly enhancing the anti-overturning ability and anti-displacement ability, improving the stability during the use of the searchlight, and can be folded when not in use, which is convenient for on-vehicle transportation or storage.

[0054] In Figure 1 、 Figure 4 、 Figure 5 、 Figure 9 and Figure 10 In the middle: And the limiting groove B805 includes a short inclined groove and a straight groove located at one end of the short inclined groove.

[0055] Specifically, when the displacement frame 704 moves vertically upward, it synchronously drives the vertical plate 801 to move vertically upward. During the process that the limiting member B803 moves from the short inclined groove into the straight groove, the support leg 804 makes a rapid flip with the support shaft 806 as the axis, and the anti-slip plate 802 is in close contact with the ground. During the process that the limiting member B803 moves into the straight groove and the vertical plate 801 continues to move upward, the support leg 804 and the anti-slip plate 801 maintain a stable support state.

[0056] In Figure 1 、 Figure 2 、 Figure 4 、 Figure 、 ​ and ​Chinese: And the anti-slip plate 802 includes a plate body and an anti-slip pad provided at the bottom end of the plate body, and the anti-slip pad is used for the frictional force between the plate body and the ground. The end of the anti-slip pad away from the plate body is provided with a serrated structure for significantly increasing the static friction coefficient, and the anti-slip pad is made of anti-slip rubber material.

[0057] Specifically, through the cooperation of the anti-slip pad and the serrated structure, the frictional force between the plate body and the ground can be increased, thereby improving the anti-overturning ability and anti-displacement ability of the searchlight.

[0058] Start the servo motor 9, so that the output end of the servo motor 9 drives the rotating shaft 10 to rotate. Through the sliding action of the displacement sleeve A603 and the rotating shaft 10, the displacement sleeve A603 and the support cylinder 5 drive the main lamp 2 to quickly rise to the highest point. During this process, the vertical plate 801 synchronously moves upward vertically. Through the rotating action of the support leg 804 and the support plate 807 and the sliding action of the vertical plate 801 and the support leg 804, when the limiting member B803 at one end of the vertical plate 801 moves from the short inclined groove into the straight groove, the support leg 804 makes a rapid flip with the support shaft 806 as the axis, and makes the anti-slip plate 802 closely contact the ground, thereby expanding the support area and improving the anti-overturning ability and anti-displacement ability;

[0059] At the same time, through the sliding action of the displacement sleeve B703 and the rotating shaft 10, the displacement sleeve B703 and the displacement frame 704 make vertical movement. Through the rotating action of the support rod 705 and the displacement frame 704 and the sliding action with the side plate 707, the support rod 705 drives the side lamp 3 to deflect with the hinge seat as the axis, so that the four side lamps 3 are synchronously radially expanded within a certain range according to the actual use requirements, so as to cooperate with the main lamp 2 to form vertical and horizontal two-way lighting coverage, improving the lighting effect;

[0060] The content not described in detail in this specification belongs to the prior art well known to those skilled in the art.
