Description

Technical Field

[0001] This utility model relates to the field of municipal road lighting facility maintenance technology, and in particular to a lifting hoist vehicle for street light maintenance. Background Technology

[0002] The street light maintenance lifting platform truck is a special vehicle designed specifically for street light inspection and maintenance operations. Its core structure includes a lifting platform (or platform) that can be flexibly raised and moved, and is equipped with a hydraulic or mechanically driven lifting mechanism, a mobile chassis, and safety protection devices.

[0003] A search revealed Chinese Patent Publication No. CN202643265U, which discloses a lifting platform with a detachable guardrail. The lifting platform includes a base, a scissor lift device, and a lifting platform. It also includes a crane and a guardrail, with the guardrail connected to the lifting platform and the crane connected to the base. The advantages of this lifting platform with a detachable guardrail are that the connection between the guardrail and the lifting platform is detachable, allowing users to choose whether to install the guardrail as needed. The crane facilitates loading and unloading of goods. However, it has limitations in its operating range (it cannot simultaneously handle horizontal displacement and vertical lifting) and cannot meet the continuous operation requirements of densely packed streetlight clusters. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a lifting crane for street light maintenance, aiming to improve the problem that the existing technology cannot meet the continuous operation requirements of dense street light groups.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lifting crane for street light maintenance, comprising a moving device, a top plate being provided on the top of the moving device, a translation mechanism being provided on the top of the top plate being used for translation, a fixing mechanism being provided on the top of the translation mechanism being used for storing tools, and a lifting mechanism being provided on the top wall of the moving device being used for lifting the top plate being used for lifting the top plate.

[0006] The translation mechanism includes a movable plate, which is disposed on the top of the top plate. Sliders are fixedly connected to the front and rear sides of the bottom wall of the movable plate. Slide grooves are provided on the front and rear sides of the top wall of the top plate. The sliders are slidably connected to the slide grooves. A drive assembly is provided inside the top plate.

[0007] Through the above technical solution: the mobile device serves as the basic supporting structure, the lifting mechanism can drive the top plate to rise and fall to adjust the working height, and the slider at the bottom of the mobile plate slides along the groove on the top wall of the top plate to ensure smooth translation.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a motor, which is fixedly connected inside the top plate. A gear is fixedly connected to the output end of the motor. A rack is fixedly connected to the bottom wall of the movable plate. A square groove is provided in the middle of the top wall of the top plate. The gear and the rack are meshed together.

[0010] The above technical solution involves a motor driving a gear to rotate, which in turn causes the gear and rack to interact, thus moving the rack. Both the gear and rack are made of high-strength alloy steel and are driven at a moderate speed. The movement of the rack then causes the moving plate to shift.

[0011] As a further description of the above technical solution:

[0012] The fixing mechanism includes a placement slot, which is located at the front and rear ends of the right side of the top wall of the movable plate. A storage box is provided inside the placement slot, and a fixing component is provided on the top of the top plate.

[0013] The above technical solution allows for the placement of storage boxes in the slots.

[0014] As a further description of the above technical solution:

[0015] The fixing component includes a pressure block that penetrates the front and rear sides of the inner top wall of the placement slot. A spring is fixedly connected to the bottom wall of the placement slot. A connecting plate is rotatably connected to the outer wall of the pressure block. A connecting block is rotatably connected to the outer wall of the connecting plate. The connecting block is fixedly connected inside the movable plate. A top rod is rotatably connected to the end of the connecting plate. Multiple fixing blocks are fixedly connected at equal intervals on the right side of the top wall of the movable plate. A locking block is slidably connected to the adjacent side of the outer wall of the multiple fixing blocks. Multiple springs are equidistantly installed on the opposite side of the outer wall of the multiple locking blocks. The top rod is slidably connected to the locking block. A locking groove is opened on the front and rear sides of the lower middle part of the outer wall of the storage box. The locking block engages with the locking groove.

[0016] Through the above technical solution: the storage box applies pressure to the pressure block by its own weight, causing the pressure block to compress the spring and move downwards. This process drives the connecting plate 1 to rotate around the connecting block as a fulcrum, causing the top rod at the end of the connecting plate 1 to slide in the fixed block and push the locking block to stretch the spring 2. The locking block then locks into the slot of the storage box, thereby achieving fixation. This can effectively resist the vibration and bumps generated during vehicle movement or operation, prevent the storage box from accidentally falling off, and ensure the safety of tool storage.

[0017] As a further description of the above technical solution:

[0018] The lifting mechanism includes a base plate, which is fixedly connected to the top wall of the moving device. A hydraulic rod is fixedly connected to the left side of the top wall of the base plate. A movable block is fixedly connected to the output end of the hydraulic rod. Connecting plates two are rotatably connected to the front and rear sides of the outer wall of the movable block. Connecting plates two are slidably connected to the base plate. Connecting plates three are rotatably connected to adjacent sides of the inner wall of the base plate. Connecting plates three are rotatably connected to the ends of multiple connecting plates two. Connecting plates two are rotatably connected to the ends of multiple connecting plates three. Connecting plates three are rotatably connected to the middle of the outer wall of connecting plates two. The bottom wall of the top plate one is fixedly connected to the top plate two. The top connecting plate two is rotatably connected to the left side of the outer wall of the top plate two. The top connecting plate three is slidably connected to the top plate two.

[0019] Through the above technical solution: when the hydraulic rod is activated, the hydraulic rod drives the movable block to move, which in turn causes one end of the connecting plate two to slide on the base plate, while simultaneously driving the other end of the connecting plate three to rotate. The middle of the connecting plate three and the connecting plate two rotate relative to each other, forming a scissor structure, which causes the structure to extend and rise. At the top of the scissor structure, the connecting plate two rotates on the top plate two, while the connecting plate three slides on the outer wall of the top plate two, thereby realizing the lifting of the top plate one. When the hydraulic rod shortens, the scissor structure folds and lowers accordingly, driving the top plate one to descend, completing the lifting and lowering process of the top plate one.

[0020] As a further description of the above technical solution:

[0021] The rack is disposed on the top of the gear and is disposed inside the square groove.

[0022] Through the above technical solution: the gear drives the rack above to move, and the rack slides in the square groove.

[0023] As a further description of the above technical solution:

[0024] The top rod is slidably connected inside the fixed block, and the end of the second spring is fixedly connected to the inner wall of the fixed block.

[0025] With the above technical solution: the push rod slides inside the fixed block, and the second spring is fixed inside the fixed block.

[0026] As a further description of the above technical solution:

[0027] Limiting grooves are provided on the front and rear sides of the top wall of the top plate one. Limiting blocks are slidably connected to the inner walls of the limiting grooves. The limiting blocks are fixedly connected to the bottom wall of the movable plate. A guardrail is provided on the top of the top plate one. The guardrail is fixedly connected to the top wall of the movable plate.

[0028] Through the above technical solution: the limiting block on the moving plate slides in the limiting groove, which can restrict and guide the moving plate's path, prevent it from falling off the top plate, and ensure the stability and positional accuracy of the moving plate during movement. The guardrail provides safety protection to reduce the risk of damage to items or people caused by accidental collisions.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the motor drives the gear to rotate, which in turn drives the rack to move. The movement of the rack causes the moving plate to move accordingly. At the same time, the slider at the bottom of the moving plate slides in the top wall groove of the top plate to ensure the stability of the translation process. Through the coordinated action of lifting and translation, the needs of different positions in street light maintenance work can be met.

[0031] 2. In this utility model, the storage box is placed in the placement slot and pressed down by its own weight. The pressure block compresses the spring and moves down together, causing the connecting plate to rotate around the connecting block as the fulcrum. This causes the top rod to slide in the fixed block, pushing the locking block to stretch the spring and lock it into the slot of the storage box to complete the fixation. This can resist the vibration and bumps when the vehicle moves or during operation, prevent the storage box from falling off accidentally, and ensure the safe storage of tools.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The slider 302 is slidably connected to the sliding groove 303. The slider 302 at the bottom of the movable plate 301 slides along the sliding groove 303 on the top wall of the top plate 2 to ensure smooth translation. The top plate 2 is provided with a drive assembly 304.

[0042] The drive assembly 304 includes a motor 3041, which is fixedly connected inside the top plate 2. A gear 3042 is fixedly connected to the output end of the motor 3041. The motor 3041 drives the gear 3042 to rotate. A rack 3043 is fixedly connected to the bottom wall of the moving plate 301. A square groove 3044 is provided in the middle of the top wall of the top plate 2. The gear 3042 and the rack 3043 are meshed and connected. The gear 3042 drives the rack 3043 to move. The gear 3042 and the rack 3043 are made of high-strength alloy steel. The rack 3043 drives the moving plate 301 to move. The rack 3043 is located on top of the gear 3042 and inside the square groove 3044.

[0043] Specifically, the motor 3041 drives the gear 3042 to rotate, thereby enabling the gear 3042 to perform medium-speed transmission with the rack 3043. The rack 3043 is responsible for pushing the moving plate 301 to move. The slider 302 at the bottom of the moving plate 301 slides in the top wall groove 303 of the top plate 2 to ensure the smoothness of the translation process. Through the coordinated action of lifting and translation, the needs of different positions in street light maintenance work can be met.

[0044] Reference Figure 2 , Figure 3 and Figure 5 The fixing mechanism 4 includes a placement slot 401, which is opened at the front and rear ends of the right side of the top wall of the movable plate 301. A storage box 402 is provided inside the placement slot 401, and the storage box 402 is placed into the placement slot 401. A fixing component 403 is provided on the top of the top plate 2.

[0045] The fixing component 403 includes a pressure block 4031, which extends through the front and rear sides of the inner top wall of the placement groove 401. A spring 4032 is fixedly connected to the bottom wall of the placement groove 401. The pressure block 4031 compresses the spring 4032 and moves downward. A connecting plate 4033 is rotatably connected to the outer wall of the pressure block 4031. A connecting block 4034 is rotatably connected to the outer wall of the connecting plate 4033. The pressure block 4031 drives the connecting plate 4033 to rotate around the connecting block 4034 as a fulcrum. The connecting block 4034 is fixedly connected inside the moving plate 301. A push rod 4035 is rotatably connected to the end of the connecting plate 4033. Multiple fixing blocks 4036 are equidistantly fixed to the right side of the top wall of the moving plate 301. Each of the adjacent sides of the outer wall of 036 is slidably connected with a locking block 4037. Multiple springs 4038 are equidistantly installed on the outer walls of the multiple locking blocks 4037 on the side away from each other. The top rod 4035 at the end of the connecting plate 4033 slides in the fixed block 4036 and pushes the locking block 4037 to stretch the springs 4038. The top rod 4035 is slidably connected to the locking block 4037. The lower middle part of the outer wall of the storage box 402 is provided with a slot 4039 on both the front and rear sides. The locking block 4037 engages with the slot 4039. The locking block 4037 is locked into the slot 4039 of the storage box 402 to complete the fixation. The top rod 4035 is slidably connected to the inside of the fixed block 4036. The end of the spring 4038 is fixedly connected to the inner wall of the fixed block 4036.

[0046] Specifically, the storage box 402 is placed into its corresponding placement slot 401. The storage box 402, by its own weight, presses against the pressure block 4031, causing the pressure block 4031 to compress the spring 4032 and move downward. At the same time, it drives the connecting plate 4033 to rotate around the connecting block 4034 as a fulcrum. This rotation causes the push rod 4035 at the end of the connecting plate 4033 to slide in the fixing block 4036 and push the locking block 4037 to stretch the spring 4038. Finally, the locking block 4037 is locked into the slot 4039 of the storage box 402 to achieve fixation. This mechanism can effectively resist the vibration and bumps generated by the vehicle during movement or operation, prevent the storage box 402 from falling off accidentally, and thus ensure the safe storage of tools.

[0047] Reference Figure 1 , Figure 3 and Figure 4The lifting mechanism 5 includes a base plate 503, which is fixedly connected to the top wall of the moving device 1. A hydraulic rod 501 is fixedly connected to the left side of the top wall of the base plate 503. A movable block 502 is fixedly connected to the output end of the hydraulic rod 501. The hydraulic rod 501 drives the movable block 502 to move. Connecting plates 2 and 3 are rotatably connected to the front and rear sides of the outer wall of the movable block 502. The connecting plates 2 and 3 are slidably connected to the base plate 503. Connecting plates 3 and 4 are rotatably connected to adjacent sides of the inner wall of the base plate 503. The connecting plates 3 and 4 are rotatably connected to the ends of the multiple connecting plates 2 and 3. The connecting plates 3 and 4 are rotatably connected to the ends of the multiple connecting plates 3 and 4. The connecting plates 3 and 4 are rotatably connected to the middle of the outer wall of the connecting plates 2 and 504. The bottom wall of the top plate 1 is fixedly connected to... The top plate 2 has a top plate 506, and a top connecting plate 2 504 is rotatably connected to the left side of the outer wall of the top plate 2 506. The top connecting plate 3 505 is slidably connected to the top plate 2 506. Limiting grooves 6 are opened on the front and rear sides of the top wall of the top plate 2. Limiting blocks 7 are slidably connected to the inner wall of the limiting grooves 6. The limiting blocks 7 are fixedly connected to the bottom wall of the moving plate 301. The limiting blocks 7 of the moving plate 301 slide in the limiting grooves 6, which can limit and guide the movement trajectory of the moving plate 301, prevent it from falling off the top plate 2, and thus ensure the stability and positional accuracy of the moving plate 301 during movement. A guardrail 8 is set on the top of the top plate 2. The guardrail 8 is fixedly connected to the top wall of the moving plate 301. The guardrail 8 is used to provide safety protection and reduce the risk of damage to items or personnel caused by accidental collisions.

[0048] Specifically, during lifting, the hydraulic rod 501 is activated, which drives the movable block 502 to move. The movable block 502 drives one end of the connecting plate 2 504 to slide on the base plate 503, while the other end drives the cross-distributed connecting plate 3 505 to rotate. The connecting plate 3 505 and the middle of the connecting plate 2 504 also rotate to form a scissor structure, which unfolds and raises the scissor structure. The top connecting plate 2 504 rotates on the top plate 2 506, while the connecting plate 3 505 slides on the outer wall of the top plate 2 506, thereby lifting the top plate 1 2. When the hydraulic rod 501 shortens, the scissor structure folds and lowers, driving the top plate 1 2 to descend, thus realizing the lifting and lowering of the top plate 1 2. The limiting block 7 of the moving plate 301 slides in the limiting groove 6, which can limit and guide the movement trajectory of the moving plate 301 to prevent it from detaching from the top plate 1 2, thereby ensuring the stability and positional accuracy of the moving plate 301 during movement. The guardrail 8 is used to provide safety protection and reduce the risk of damage to objects or personnel due to accidental collisions.

[0049] Working principle: Motor 3041 drives gear 3042 to rotate, gear 3042 drives rack 3043 to move. Gear 3042 and rack 3043 are made of high-strength alloy steel and are driven at medium speed. Rack 3043 drives moving plate 301 to move. At the same time, slider 302 at the bottom of moving plate 301 slides along the groove 303 on the top wall of top plate 2 to ensure smooth translation. Through the coordination of lifting and translation, the operation needs of different positions during street light maintenance are met.

[0050] Place the storage box 402 into the placement slot 401. The storage box 402 presses down on the pressure block 4031 under its own weight. The pressure block 4031 compresses the first spring 4032 and moves downward, causing the first connecting plate 4033 to rotate with the connecting block 4034 as the fulcrum. This causes the push rod 4035 at the end of the first connecting plate 4033 to slide in the fixing block 4036 and push the locking block 4037 to stretch the second spring 4038. This causes the locking block 4037 to lock into the slot 4039 of the storage box 402 and complete the fixation. This can effectively resist the vibration and bumps when the vehicle moves or during operation, prevent the storage box 402 from falling off accidentally, and ensure the safe storage of tools. When taking it out, lift the storage box 402 so that the first spring 4032 rebounds to the pressure block 4031. The push rod 4035 retracts, causing the locking block 4037 to disengage from the slot 4039, and the storage box 402 can be taken out.
