Description

Technical Field

[0001] This utility model belongs to the field of crane driver visibility assistance technology, and in particular relates to a crane cab visibility assistance device. Background Technology

[0002] A crane is a multi-action lifting machine used for vertically lifting or horizontally moving heavy objects. It is widely used in industries, construction, logistics and other fields. It mainly realizes two major actions: vertical lifting and horizontal handling of heavy objects. Through mechanical structure, it converts energy into displacement of heavy objects. Unlike lifting equipment in one direction, its boom or lifting device can flexibly rotate, change amplitude or move within a certain space, covering a wider range of operations.

[0003] Due to the inherent structural limitations of cranes, the operator's cab has a limited field of vision and certain blind spots, which is not conducive to safe operation. As cranes are large-scale operating equipment, there are certain dangers during operation, requiring real-time recording of the working environment and workflow. However, existing cranes do not have these functions, making their use inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a crane cab visibility aid that solves existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a crane cab visibility aid device, comprising: a vehicle body, a support arm rotatably connected to the top of the vehicle body, a counterweight fixedly installed at one end of the support arm, support arms symmetrically rotatably connected to both sides of the vehicle body, a cab fixedly installed on one side of the support arm, and an auxiliary mechanism fixedly installed at the end of the support arm, and the auxiliary mechanism is electrically connected to the cab; the auxiliary mechanism includes a connecting frame fixedly installed at the end of the support arm, a mounting base fixedly installed on one side of the connecting frame, a fixed seat fixedly installed at the top of the mounting base, and a drive motor fixedly installed at the top of the fixed seat.

[0006] Furthermore, the auxiliary mechanism also includes a drive gear rotatably connected to one end of the fixed base, a driven gear rotatably connected to the other end of the fixed base, and the driven gear meshing with the drive gear. The output end of the drive motor passes through the side wall of the fixed base and is fixedly connected to the drive gear. A synchronous belt structure is symmetrically rotatably connected to the bottom of the fixed base. Swing arms are rotatably connected to both ends of the mounting base, and the ends of the swing arms are engaged with the ends of the synchronous belt structure. A camera device is rotatably connected to the end of the swing arm away from the mounting base. When the device is in use, the drive motor drives the drive gear and the driven gear to rotate, thereby driving the synchronous belt structure to rotate synchronously. As the synchronous belt structure rotates, it can drive the two swing arms to unfold, thereby unfolding the camera device. As the camera device unfolds, it can cover a wider field of view. At this time, the operator can display the recorded image of the camera device in real time through the display screen inside the cab, further increasing the convenience of the operator when using it.

[0007] Furthermore, the swing arm is L-shaped, which allows it to be stably stored on one side of the mounting base when the swing arm is rotated and retracted, increasing the stability of the device during storage.

[0008] Furthermore, a fixing block is fixedly installed on the side of the mounting base away from the connecting frame. Cleaning channels are provided on both sides of the fixing block, and the cleaning channels are fixedly connected to the mounting base. In order to increase the cleanliness of the camera device during use, a cleaning channel is provided on the path of the swing arm's rotation and storage, which can quickly clean the end of the camera device. The fixing block can shield the cleaning channel.

[0009] Furthermore, a friction wheel is fixedly installed at the top of the camera device, and friction rings are fixedly installed on both sides of the fixing block. The friction rings and the friction wheel are in frictional engagement. When the auxiliary mechanism rotates and retracts, the swing arm rotates around the end of the mounting base. During the rotation, the friction wheel at the top of the camera device will squeeze and rub against the friction rings, thereby driving the camera device to rotate. This also causes the contact end between the camera device and the cleaning channel to rotate, thus better cleaning the camera device.

[0010] Furthermore, the swing arm has several mounting slots equidistantly arranged in a ring shape at one end near the camera device. A limiting post is slidably connected inside the mounting slot, and an auxiliary spring is sleeved at the end of the limiting post. The auxiliary spring is located inside the mounting slot. The surface of the friction wheel has equidistant locking holes that engage with the limiting post. In order to increase the stability of the camera device during operation, the limiting post slidably connected inside the swing arm can engage with the locking holes on the friction wheel. The auxiliary spring sleeved on the outside of the limiting post allows the limiting post to elastically extend and retract, allowing the limiting post and the friction wheel to press against each other. This can restrict the friction wheel when it is not rotating, thereby increasing the working stability of the camera device.

[0011] Furthermore, several lightweight grooves are equidistantly arranged at the bottom end of the swing arm. The lightweight grooves at the bottom end of the swing arm can reduce the weight of the swing arm itself and reduce the production cost of the swing arm, making it easier to assemble the device.

[0012] This utility model has the following beneficial effects: 1. This utility model, through the setting of an auxiliary mechanism, can quickly unfold the camera device when the device is in use, thereby allowing the two camera devices to cover a wider field of view. This enables the staff to have real-time control over the field of view around the device, thereby increasing the safety of the device during use. In addition, the camera device can record the surrounding field of view in real time, which is convenient for the staff to review.

[0013] 2. This utility model utilizes the frictional engagement between the friction wheel and the friction ring to allow the camera device to pass through the cleaning channel during the rotation of the swing arm, and to clean the camera device through the cleaning channel. The setting of the limiting post can restrict the position of the friction wheel, thereby ensuring the stability of the camera device during operation and further improving the convenience of the device during use.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model relates to a crane cab visibility aid device, comprising: a vehicle body 1, a support arm 2 rotatably connected to the top of the vehicle body 1, a counterweight block 3 fixedly installed at one end of the support arm 2, support arms 4 symmetrically rotatably connected to both sides of the vehicle body 1, a cab 5 fixedly installed on one side of the support arm 2, and an auxiliary mechanism 6 fixedly installed at the end of the support arm 2, and the auxiliary mechanism 6 is electrically connected to the cab 5; the auxiliary mechanism 6 includes a connecting frame 7 fixedly installed at the end of the support arm 2, a mounting base 8 fixedly installed on one side of the connecting frame 7, a fixing base 9 fixedly installed at the top of the mounting base 8, and a drive motor 10 fixedly installed at the top of the fixing base 9.

[0020] The auxiliary mechanism 6 further includes a drive gear 11 rotatably connected to one end of the fixed base 9, and a driven gear 12 rotatably connected to the other end of the fixed base 9, with the driven gear 12 meshing with the drive gear 11. The output end of the drive motor 10 passes through the side wall of the fixed base 9 and is fixedly connected to the drive gear 11. A synchronous belt structure 13 is symmetrically rotatably connected to the bottom end of the fixed base 9. Both ends of the mounting base 8 are rotatably connected to swing arms 14, the ends of which are engaged with the ends of the synchronous belt structure 13. The swing arms 14 are located away from the mounting base 8. One end of the device is rotatably connected to a camera device 15. When the device is in use, the drive motor 10 drives the drive gear 11 and the driven gear 12 to rotate, which in turn drives the synchronous belt structure 13 to rotate synchronously. As the synchronous belt structure 13 rotates, it can drive the two swing arms 14 to unfold, thereby enabling the camera device 15 to unfold. As the camera device 15 unfolds, it can cover a wider field of view. At this time, the operator can display the recorded images of the camera device 15 in real time through the display screen inside the cab 5, further increasing the convenience for the operator when using it.

[0021] The swing arm 14 is L-shaped. When the swing arm 14 is rotated and stored, it can be stably stored on one side of the mounting base 8, which increases the stability of the device when stored.

[0022] A fixing block 17 is fixedly installed on the side of the mounting base 8 away from the connecting frame 7. Cleaning channels 19 are provided on both sides of the fixing block 17, and the cleaning channels 19 are fixedly connected to the mounting base 8. In order to increase the cleanliness of the camera device 15 during use, a cleaning channel 19 is provided on the device along the rotation and storage path of the swing arm 14, which can quickly clean the end of the camera device 15. The fixing block 17 can shield the cleaning channel 19.

[0023] A friction wheel 16 is fixedly installed at the top of the camera device 15, and friction rings 18 are fixedly installed on both sides of the fixing block 17. The friction rings 18 and the friction wheel 16 are in frictional engagement. When the auxiliary mechanism 6 is rotating and retracted, the swing arm 14 rotates around the end of the mounting base 8. During the rotation, the friction wheel 16 at the top of the camera device 15 will squeeze and rub against the friction rings 18, thereby driving the camera device 15 to rotate. This also causes the contact end between the camera device 15 and the cleaning channel 19 to rotate, thus better cleaning the camera device 15.

[0024] The swing arm 14 has several mounting slots 20 arranged in a ring at equal intervals near the end of the camera device 15. A limiting post 21 is slidably connected inside the mounting slot 20. An auxiliary spring 22 is sleeved at the end of the limiting post 21 and is located inside the mounting slot 20. The surface of the friction wheel 16 has locking holes 23 equidistantly arranged to engage with the limiting post 21. In order to increase the stability of the camera device 15 during operation, the limiting post 21 slidably connected inside the swing arm 14 can be inserted into the locking holes 23 on the friction wheel 16. The auxiliary spring 22 sleeved outside the limiting post 21 allows the limiting post 21 to elastically extend and retract, allowing the limiting post 21 to press against the friction wheel 16. This can restrict the friction wheel 16 when it is not rotating, thereby increasing the working stability of the camera device 15.

[0025] The bottom end of the swing arm 14 is provided with several lightweight grooves at equal intervals. The lightweight grooves at the bottom end of the swing arm 14 can reduce the weight of the swing arm 14 itself and reduce the production cost of the swing arm 14, and facilitate the assembly of the device.
