Description

A movable searchlight stand

Technical field

The invention relates to a searchlight holder, specifically a movable searchlight holder.

Background technique

A searchlight, as a lighting device, has a powerful light source and a concave mirror that concentrates light and projects it in a specific direction. Since its birth, it has been for long-distance lighting and search. But its powerful lighting capabilities are matched by its larger size and weight. For ease of operation, most searchlights are equipped with side support rods or movable carriers. Large searchlights are even equipped with special vehicles as their carriers.

Since the birth of searchlights, they have been widely used in national defense, military, justice (prisons, detention centers, labor camps, labor camps), water conservancy (sluices, reservoirs, hydropower stations, hydrological stations), electric power and other departments, as well as large industrial and mining enterprises, large Engineering construction sites, oil fields, steel plants, airports, docks, maritime or wild search and rescue and other places. Corresponding to its wide range of applications is a wide variety of searchlight stands. In order to meet the working conditions of searchlights in different environments, the light frame has also derived a variety of structures.

Among them, marine searchlights are devices used for lighting when fishing boats are traveling on the sea at night. Since the hull travels on the sea for a long time, the light stand used to install the searchlight needs to have the performance of resisting the bumps of the hull, such as installing side support rods around the light stand. Prevent damage to the searchlight due to bumps in the hull. However, when the fishing boat is traveling, the searchlight and its corresponding light holder not only need to withstand the force and moment caused by the bumps of the hull, but also need to withstand the impact of wind resistance on the searchlight and light holder under different navigation conditions. Since the light holder is resistant to The bending moment capacity is limited. If the wind resistance reaches a certain predetermined value or even exceeds the preset value, the bending moment stress (shear stress) endured by the light holder is likely to exceed the allowable stress and cause the light holder to bend and break. In addition, due to Large in size, light stands are generally welded to the hull, which limits the range of use of the light stands.

Contents of the invention

In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a movable base, and when the wind resistance is too large, the lamp holder automatically shrinks, thereby shortening the force arm and reducing the force area, so as to reduce the shear stress. A removable searchlight stand that is reduced in size and thereby protects the light stand.

In order to achieve the above object, the present invention provides the following technical solution: including a bracket for installing a searchlight and a plurality of circumferentially symmetrically distributed side support rods for supporting the bracket, which is characterized in that: the bracket includes in sequence from bottom to top. An extension rod that raises the horizontal position of the searchlight and an installation mechanism for installing the searchlight. A connecting rod joint for connecting the two is provided between the extension rod and the installation mechanism. The extension rod has an up and down telescopic function. And the radius of the sleeve rod decreases sequentially from bottom to top. The lower end of the sleeve rod is provided with a base for installing the sleeve rod. The base is located at the bottom end of the sleeve rod and is provided with a shape and size that matches the shape and size of the bottom end of the sleeve rod. The cavity mouth, the base is provided with a recovery cavity for recovering the shrunk sleeve rod downward along the cavity mouth, and the base is located on the periphery of the cavity mouth and is provided with a recovery cavity for the sleeve rod to slide in the up and down direction and can be connected with the cavity mouth. The bottom end of the set rod passes through a guide fixed ring that is friction-fitted. The two free ends of each side support rod are respectively hinged to the edge of the base and the connecting rod joint. Each side support rod includes an upper support rod and a lower support rod. The upper support rod slides along the length direction of the lower support rod and is inserted into the lower support rod. The upper support rod is provided with an elastic clamping block away from the connecting rod joint end for fixed cooperation with the lower support rod. The support rod is provided with an embedded hole corresponding to the position of the elastic clamping block, which is embedded and positioned with the elastic clamping block. The elastic clamping block includes a positioning clamping block and a compression spring provided on the positioning clamping block for resetting the positioning clamping block to the outside. The positioning block is provided with arc-shaped guide walls along both side walls in the length direction of the corresponding side support rod, and the lower end of the base is provided with a movable roller for moving the base.

By adopting the above technical solution, the bracket is set up to provide a mounting position for the searchlight, which facilitates the installation of the searchlight. The side support rods are evenly distributed around the bracket to support the bracket in the horizontal direction to prevent the bracket from being affected by the force generated by wind and bumps. Broken or bent, the bracket includes an extension rod and a mounting mechanism. The setting of the extension rod raises the overall horizontal position of the mounting mechanism, so that the searchlight installed on the mounting mechanism has a farther illumination distance due to the rise in the horizontal position. The base of the lower end of the extension rod Setting, the light stand does not need to be installed on the hull, and the base can be moved as needed, making it more convenient to use. The extension rod is a sleeve rod with a retractable function. Since it has a telescopic function, it can be retracted when needed. shrink, thereby achieving the function of increasing space utilization. The cavity and recovery cavity are set up on the base, and the cavity is located at the lower end of the sleeve rod, so that the sleeve rod can directly enter the recovery cavity through the cavity. The two free ends of the side support rods are respectively Compared with the fixed connection of the two ends of the side support rod, the hinged setting makes the side support rod only subject to tensile and compressive stress without generating shear stress, preventing the side support rod from breaking. In addition, the hinged setting makes the subsequent upper support rod and When the lower support rod shrinks, the two free ends can rotate stably. The arrangement of the upper support rod and the lower support rod allows the side support rods to slide relatively along the length direction, realizing the contraction of the side support rods, and the elastic clamping block and the corresponding The setting of the embedded hole makes the upper and lower support rods in a clamped state when the extension rod is required to be in an extended state, thereby ensuring the stability of the extension rod. Finally, the setting of the arc-shaped guide wall on the positioning block, When subjected to external force, it has a tendency to move inward, and the spring is compressed inward to make the elastic clamping block break away from the embedded hole, causing the extension rod to lose its supporting force and shrink under the action of gravity. In addition, the setting of the roller makes The base can be moved, eliminating the need to set up light stands wherever lighting is needed, and the range of use has been improved. The advantage is that the extension rod uses a sleeve rod with a shrinking function. When the searchlight needs to be used, the sleeve rod is extended to raise the horizontal position of the searchlight, thereby ensuring the area that the searchlight can illuminate. However, since the extension rod is a sleeve rod Therefore, the set rod can easily shrink automatically under the action of gravity and affect its use. Therefore, the side support rod is set to support the set rod when it is in an extended use state to prevent the set rod from automatically shrinking due to gravity. In addition, The side support rod is composed of an upper support rod and a lower support rod, and is fixed in the embedded hole through an elastic clamping block. When the wind force is too strong or the sleeve rod needs to be retracted, the wind or artificial arc-shaped The guide wall exerts force to make the positioning block squeeze the spring and move inward, thereby breaking away from the embedded hole and losing its fixing effect. Later, because the upper support rod can slide relative to the lower support rod, the side support rod loses its support for the extension rod. , the extension rod shrinks under the action of gravity, and the side support rod shrinks as the two hinged ends rotate, causing the horizontal position of the searchlight to lower. When the horizontal position is lowered, the overall light frame not only reduces the area affected by wind force, but also The shortened force arm reduces the shear stress generated, thus automatically protecting the lamp stand. Finally, the setting of the recovery cavity not only makes the extension rod easy to recycle, but also increases the height at which the extension rod can be lowered, shortening the moment arm and reducing the The force-bearing area also has protective significance.
