Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for engineering construction, specifically a safety auxiliary tool for lighting engineering construction. Background Technology

[0002] Lighting engineering refers to the design, technology, and engineering of using natural or artificial lighting systems to meet the lighting requirements of a specific lighting environment. The lighting requirements mainly include the illuminance, brightness, color rendering index, and visual effects of the lighting environment on the illuminated surface. The lighting environment includes indoor spaces and outdoor spaces such as roads, squares, scenic spots, parks, and buildings. During the lighting construction process, it is necessary to install lighting lamps on lamp tubes. For lamp tubes that are not very tall, ladders or other climbing devices are usually set up to assist in the installation of the lamp body.

[0003] In a Chinese patent for a lighting engineering construction auxiliary safety tool (patent number: CN218324710U), the device includes: a support block, which is set inside the ladder. A moving groove is set in the middle of the front side of the support block. Sliding grooves are set on both sides of the inner wall of the moving groove. An adjustment device is set inside the moving groove. A clamping device is threaded on the outer surface of the adjustment device. The device controls the output shaft of the first servo motor to rotate through an external power source, which drives the threaded rod to rotate, so that the two clamping devices on the left and right move towards the middle to clamp the lamp post. After the user climbs the ladder, he rotates the screw to engage the limiting device to move and lock the lamp post. This device has a simple structure and strong practicality. It can lock the ladder on the lamp post, thereby ensuring the safety of construction personnel when climbing. However, the device does not set an auxiliary safety mechanism between the ladder and the worker. During the construction process on the top of the street light, the worker is prone to fall off the ladder due to mistakes, which still poses a safety hazard. Summary of the Invention

[0004] The purpose of this utility model is to provide a safety aid tool for lighting engineering construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety auxiliary tool for lighting engineering construction, comprising a ladder body, a clamping mechanism fixedly connected to the side of the ladder body near the lamp post, sliding grooves fixedly connected to both side walls of the ladder body, a movable block slidably connected to the inner wall of the sliding groove, a sliding opening opened on the side of the sliding groove away from the ladder body, one end of the movable block extending to the outside of the sliding opening, the movable block having a hollow structure, a locking mechanism provided in the movable block, a locking groove corresponding to the locking mechanism opened at the upper end of the inner side wall of the sliding groove, safety ropes fixedly connected to the outer walls of both movable blocks, and buckle belts fixedly connected to the ends of the two safety ropes away from the movable blocks.

[0006] As a further embodiment of this utility model: the locking mechanism includes a pull rod inserted into and slidably connected to the outer end of the moving block, a pull block fixedly connected to the outer end of the pull rod, a slide plate fixedly connected to the inner end of the pull rod, a compression spring fixedly connected between the slide plate and the inner wall of the moving block, the compression spring being sleeved on the outer side of the pull rod, a locking block fixedly connected to the side of the slide plate away from the pull rod, and one end of the locking block being inserted into a locking groove.

[0007] As a further embodiment of this utility model: the side wall of the movable block is provided with a sliding hole, and the locking block is disposed through the sliding hole.

[0008] As a further embodiment of this utility model: the clamping mechanism includes an I-shaped shell fixed to one side of the ladder body. A handwheel rod is inserted into and rotatably connected to one side of the vertical section of the I-shaped shell. A double-grooved wheel is fixedly connected to the inner end of the handwheel rod. Two bidirectional lead screws are rotatably connected to the inner walls of the two transverse sections of the I-shaped shell. A transmission wheel is fixedly connected to each of the two bidirectional lead screws. The double-grooved wheel is connected to the two transmission wheels respectively via a transmission belt. Two sets of symmetrically arranged nut blocks are threaded onto the two bidirectional lead screws. A connecting rod is fixedly connected to the front side wall of each of the two sets of nut blocks. A slot is opened on the side wall of each of the two transverse sections of the I-shaped shell. The two sets of connecting rods pass through the two slots and are fixedly connected to two sets of symmetrically arranged arc-shaped clamping plates.

[0009] As a further embodiment of this utility model, the inner wall of the vertical section of the I-shaped shell is rotatably connected to the double-grooved wheel via a rotating component.

[0010] As a further embodiment of this utility model, the inner wall of the I-shaped shell is slidably connected to the outer wall of the nut block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This is a safety auxiliary tool for lighting engineering construction. By setting up a locking mechanism, a safety rope, and a buckle belt, the buckle belt is tied to the worker's waist. Utilizing the elastic force of a compression spring, the locking block is inserted into the locking groove, which can lock the displacement of the moving block, thereby forming a fixed connection between the worker and the ladder body, thus improving the worker's safety during the lighting engineering construction process. When the worker needs to climb down the ladder body after inspecting the street light, he first pulls the pull block to move the slide plate fixed to the pull rod. At this time, the compression spring is compressed and generates elastic force until the locking block is completely separated from the locking groove. At this time, the displacement of the moving block is no longer restricted, allowing the moving block to move down in the slide bar along with the buckle belt on the worker, preventing the worker from falling due to backward leaning during the climbing process.

[0013] 2. This lighting engineering construction auxiliary safety tool, by setting up a clamping mechanism, vertically approaches the ladder body close to the lamp post. Two sets of arc-shaped clamping plates are clamped on both sides of the lamp post. Turning the handwheel rod drives the double grooved wheel to rotate. Since the double grooved wheel is transmitted to the two transmission wheels through two transmission belts, it drives the two bidirectional lead screws to rotate simultaneously. At this time, the two sets of nut blocks are displaced in opposite directions, thereby driving the two sets of arc-shaped clamping plates to clamp the lamp post, so that the ladder body is fixed on the lamp post. The operation is simpler, the fixation is more reliable, and the safety is improved. Attached Figure Description

[0020] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0021] Please see Figures 1-4In this practical embodiment, a safety auxiliary tool for lighting engineering construction includes a ladder body 1. A clamping mechanism is fixedly connected to the side of the ladder body 1 near the lamp post. Slide rails 2 are fixedly connected to both side walls of the ladder body 1. Moving blocks 3 are slidably connected to the inner walls of the slide rails 2. A sliding opening 4 is opened on the side of the slide rails 2 away from the ladder body 1. One end of the moving block 3 extends to the outside of the sliding opening 4. The moving block 3 has a hollow structure and a locking mechanism is provided in the moving block 3. A locking groove 5 corresponding to the locking mechanism is opened at the upper end of the inner side wall of the slide rails 2. Safety ropes 6 are fixedly connected to the outer walls of the two moving blocks 3. A buckle belt 7 is fixedly connected to the end of the two safety ropes 6 away from the moving blocks 3. When the worker climbs to the top of the ladder body 1, the locking mechanism is inserted into the locking groove 5 to fix the moving block 3 and the buckle belt 7 is tied to the worker's waist, thereby forming a fixed connection between the worker and the ladder body 1, which can prevent the worker from falling from the ladder body 1 during the lighting engineering construction process, thereby improving safety.

[0022] like Figure 2 and Figure 3 As shown: The locking mechanism includes a pull rod 8 inserted into and slidably connected to one side of the outer end of the movable block 3. A pull block 9 is fixedly connected to the outer end of the pull rod 8, and a sliding plate 10 is fixedly connected to the inner end of the pull rod 8. A compression spring 11 is fixedly connected between the sliding plate 10 and the inner wall of the movable block 3. The compression spring 11 is sleeved on the outer side of the pull rod 8. A locking block 12 is fixedly connected to the side of the sliding plate 10 away from the pull rod 8. One end of the locking block 12 is inserted into the locking groove 5. When the staff needs to climb down the ladder body 1 after repairing the street light, they first pull the pull block 9 to move the sliding plate 10 fixed to the pull rod 8. At this time, the compression spring 11 is compressed. When the compression spring 11 is compressed, it generates elastic force until the locking block 12 is completely separated from the locking groove 5. At this time, the displacement of the moving block 3 is no longer restricted, allowing the moving block 3 to move down in the slide bar 2 along with the buckle belt 7 on the worker's body, preventing the worker from falling due to backward leaning during the climbing process. When maintenance is required, the elastic force of the compression spring 11 is used to insert the locking block 12 into the locking groove 5, which can lock the displacement of the moving block 3, thereby forming a fixed connection between the worker and the ladder body 1, thus improving the safety of the worker during the lighting project construction process.

[0023] like Figure 3 As shown: The side wall of the movable block 3 is provided with a sliding hole, through which the locking block 12 passes to facilitate the displacement of the locking block 12.

[0024] like Figure 1 and Figure 4As shown: The clamping mechanism includes an I-shaped shell 13 fixed to one side of the ladder body 1. A handwheel rod 14 is inserted into and rotatably connected to one side of the vertical section of the I-shaped shell 13. A double-grooved wheel 15 is fixedly connected to the inner end of the handwheel rod 14. Two bidirectional lead screws 16 are rotatably connected to the inner walls of the two transverse sections of the I-shaped shell 13. Transmission wheels 17 are fixedly connected to the two bidirectional lead screws 16. The double-grooved wheels 15 are respectively connected to the two transmission wheels 17 via transmission belts 18. Two sets of symmetrically arranged nut blocks 19 are threaded onto the two bidirectional lead screws 16. Connecting rods 20 are fixedly connected to the front side walls of the two sets of nut blocks 19. The two transverse side walls of the I-shaped shell 13 are provided with slots 21, and the two sets of connecting rods 20 are respectively... Two sets of symmetrically arranged arc-shaped clamping plates 22 are fixedly connected through two slots 21. When it is necessary to inspect the top of the street lamp, the ladder body 1 is placed vertically close to the street lamp post. The two sets of arc-shaped clamping plates 22 are locked on both sides of the lamp post. The handwheel lever 14 is turned, which drives the double grooved wheel 15 to rotate. Since the double grooved wheel 15 is driven by two transmission belts 18 and two transmission wheels 17, it drives the two bidirectional screws 16 to rotate simultaneously. Since the two bidirectional screws 16 are respectively threadedly connected to two sets of nut blocks 19, the two sets of nut blocks 19 are displaced in opposite directions, which drives the two sets of arc-shaped clamping plates 22 to clamp the lamp post, so that the ladder body 1 is fixed on the lamp post. The operation is simpler, the fixation is more reliable, and the safety is improved.

[0025] like Figure 4 As shown: The vertical section of the inner wall of the I-shaped shell 13 is rotatably connected to the double groove wheel 15 through a rotating component, making the rotation of the double groove wheel 15 more stable.

[0026] like Figure 4 As shown: The inner wall of the I-shaped shell 13 is slidably connected to the outer wall of the nut block 19, which can prevent the nut block 19 from rotating axially.

[0027] Working principle: When workers are installing streetlights, they first place the ladder body 1 vertically close to the streetlight pole. Two sets of arc-shaped clamps 22 are clamped on both sides of the lamp post. Turning the handwheel 14 drives the double grooved wheel 15 to rotate. Since the double grooved wheel 15 is driven by two transmission belts 18 and two transmission wheels 17, it drives the two double-direction screws 16 to rotate simultaneously. Since the two double-direction screws 16 are threadedly connected to two sets of nut blocks 19 respectively, at this time, the two sets of nut blocks 19 are displaced in opposite directions, thereby driving the two sets of arc-shaped clamps 22 to clamp the lamp post, so that the ladder body 1 is fixed on the lamp post. The operation is simpler, the fixation is more reliable, and the safety is improved.

[0028] Then, the buckle belt 7 is tied around the worker's waist. Using the elastic force of the compression spring 11, the locking block 12 is inserted into the locking groove 5, which can lock the displacement of the moving block 3, thereby forming a fixed connection between the worker and the ladder body 1, thus improving the safety of the worker during the lighting project construction process. When the worker needs to climb down the ladder body 1 after inspecting the street light, he first pulls the pull block 9 to move the slide plate 10 fixed to the pull rod 8. At this time, the compression spring 11 is squeezed and contracted to generate elastic force until the locking block 12 is completely separated from the locking groove 5. At this time, the displacement of the moving block 3 is no longer restricted, so that the moving block 3 can follow the buckle belt 7 on the worker and move down in the slide bar 2, preventing the worker from falling due to backward leaning during the climbing process.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
