Description

Technical Field

[0001] This utility model relates to the field of frontal blind spot protection technology, specifically, to a simple frontal blind spot protection device. Background Technology

[0002] A reach stacker is short for a container reach crane. It is mainly used for stacking containers and horizontal transport within docks and yards. Compared with forklifts, it has advantages such as maneuverability, ease of operation, good stability, lower wheel pressure, higher stacking depth, and higher yard utilization. A reach stacker consists of three parts: an engineering machinery chassis, a telescopic boom, and a container spreader. The chassis includes components such as a frame, engine, cab, counterweight, and wheels. When using it, the operator sits in the cab to control the movement of the telescopic boom and the container spreader.

[0003] The overall size of the reach stacker is relatively large, and the two front wheels and two rear wheels are also quite large. Furthermore, the cab is mainly forward-facing, allowing the driver to clearly see the area near the front wheels, but not the area behind the chassis or near the rear wheels. If there are people behind the chassis or near the rear wheels, the driver may not be able to see them, which could easily lead to the chassis colliding with or the wheels hitting people. Therefore, it is necessary to improve the protection of the rear and rear wheels of the reach stacker to enhance its safety during use. Summary of the Invention

[0004] The purpose of this invention is to provide a simple protective device for blind spots in frontal hanging, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a simple protective device for the blind spot of a front-mounted crane, comprising four connecting frames, which are divided into two groups and respectively set on both sides of the front crane frame. The two connecting frames in the same group are respectively set on both sides of the rear wheel. Several side elastic steel bars are connected between the two connecting frames in the same group, and the several side elastic steel bars protect the rear wheel inside. Several rear protective components are connected between the two connecting frames in the two groups that are far from the front wheel. The several rear protective components are combined together to protect the rear side of the front crane frame and guide the object to move to both sides when encountering an obstacle.

[0006] As a further improvement to this technical solution, the connecting frame includes several polygonal plates arranged vertically. The polygonal plates are hexagonal in shape with left and right symmetry. Two of the sides are arranged in parallel, and an outer connecting plate and an inner connecting plate are fixed to the two parallel sides respectively. Side arc plates are fixedly connected to both ends of the outer connecting plate. The side arc plates and one side of the polygonal plates are fixed together, and space is left between the side arc plates and the inner connecting plates for mounting bolts.

[0007] As a further improvement to this technical solution, a set of screw holes is provided on the side arc plate, and two sets of screw holes are provided on both the inner connecting plate and the outer connecting plate. The screw holes on the inner connecting plate and the screw holes on the outer connecting plate are arranged correspondingly. A reinforcing rib is fixed between the inner connecting plate and the outer connecting plate. The reinforcing rib is fixed on the polygonal plate and is connected between the two sets of screw holes on the inner connecting plate and the outer connecting plate.

[0008] As a further improvement to this technical solution, two connecting and reinforcing plates are provided between two adjacent polygonal plates. The two inner connecting plates and the two ends of the connecting and reinforcing plates are fixedly connected by bolts, and the two outer connecting plates and the two ends of the connecting and reinforcing plates are fixedly connected by bolts. The two connecting and reinforcing plates are staggered.

[0009] As a further improvement to this technical solution, an inner connecting plate is bolted between two adjacent inner connecting plates, and a distance-extending fixing bracket is fixed at both ends of the inner connecting plate. The two distance-extending fixing brackets and the inner connecting plate form a C-shaped structure, and the ends of the distance-extending fixing brackets are bolted to the outside of the frame on both sides of the front crane.

[0010] As a further improvement to this technical solution, the two ends of the side elastic steel strip are respectively fixed to the outer connecting plates at the same height in the two connecting frames, and the middle part of the side elastic steel strip bulges away from the vehicle frame.

[0011] As a further improvement to this technical solution, the rear protective component includes a central plate, with arc-shaped rear elastic steel strips fixed at both ends of the central plate, and the other end of the rear elastic steel strips fixed to a side arc plate at the same horizontal level by bolts.

[0012] As a further improvement to this technical solution, an arc-shaped soft rubber pad is provided on the side of the middle plate away from the connecting frame, and an I-beam connecting frame is provided on the side of the middle plate close to the connecting frame. The other end of the I-beam connecting frame is fixed to the rear frame of the front crane frame. The I-beam connecting frame, the middle plate and the soft rubber pad are fixed together by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This simple blind spot protection device for frontal cranes involves installing four connecting frames on both sides of the two rear wheels, with two of them positioned at the rear and side of the frontal crane frame. Side elastic steel bars protect the rear wheels, and rear protective components protect the rear of the frame. These components are positioned at a certain distance from the frame and wheels. When a person approaches the wheels or the rear of the frame, the elastic steel bars and rear protective components can make contact with them in advance, effectively blocking them and preventing direct contact between the person and the wheels and frame. In the event of a collision, this reduces the risk of injury. Furthermore, the curved side and rear elastic steel bars can guide people or objects to one side upon contact, further reducing damage from frontal collisions. Attached Figure Description

[0018] Example 1. When a front-load crane is in operation, the driver's field of vision is mainly focused on the working area directly in front (such as the front wheels, the front side of the frame, and the cantilever), resulting in a significant blind spot between the rear wheels and the rear side of the frame. Furthermore, the rear wheels are usually directly exposed on both sides of the frame, making them susceptible to contact with external personnel or objects. Given the extremely heavy weight of the front-load crane, a run-over or collision would cause serious personal injury and property damage. Simultaneously, the driver cannot see the rear side of the frame, posing a direct collision risk to personnel or objects, potentially causing injury.

[0019] To reduce the risk of injury to personnel from collisions during operation of the reach stacker, and to prevent personnel or objects from being run over by its wheels, please refer to [link / reference needed]. Figures 1-7As shown, this embodiment provides a simple protective device for blind spots of a front-mounted crane, including four connecting frames 1. The four connecting frames 1 are divided into two groups and are respectively set on both sides of the front crane frame. Two connecting frames 1 in the same group are respectively set on both sides of the rear wheel, that is, two connecting frames 1 are set on the rear wheel near the front wheel and on the side wall of the frame, and the other is set on the rear wheel away from the front wheel and on the side of the frame near the rear. At the same time, several side elastic steel bars 3 are connected between the two connecting frames 1 in the same group. The middle of the side elastic steel bars 3 extends away from the front wheel. The frame is raised in the direction of the wheel, and several side elastic steel bars 3 protect the rear wheel inside. By raising the side elastic steel bars 3 away from the frame, the distance between the side elastic steel bars 3 and the wheel is increased to ensure that the side elastic steel bars 3 have enough space to adjust the angle and ensure the normal use of the front crane wheel. In addition, several rear protective parts 2 are connected between the two connecting frames 1 that are away from the front wheel. The several rear protective parts 2 are combined together to protect the rear side of the front crane frame and guide the object to move to both sides when encountering obstacles.

[0020] The connecting frame 1 includes several polygonal plates 11 arranged vertically. Each polygonal plate 11 is a symmetrical hexagon with two parallel sides. An outer connecting plate 13 and an inner connecting plate 12 are fixed to each of the two parallel sides. The length of the outer connecting plate 13 is greater than the length of the inner connecting plate 12. Side arc plates 14 are fixed to both ends of the outer connecting plate 13. The side arc plates 14 are fixed to one side of each polygonal plate 11. This arrangement creates a triangular structure between each pair of adjacent plates, ensuring the stability of the inner connecting plate 12 and the outer connecting plate 13. Space is provided between the side arc plates 14 and the inner connecting plate 12 for bolt installation. Operators can use this space, as well as the space below the polygonal plates 11, to insert and install bolts and observe their placement. Furthermore, a set of screw holes is provided on the side arc plate 14, and two sets of screw holes are provided on both the inner connecting plate 12 and the outer connecting plate 13. The screw holes on the inner connecting plate 12 and the screw holes on the outer connecting plate 13 are arranged correspondingly. A reinforcing rib is fixed between the inner connecting plate 12 and the outer connecting plate 13. The reinforcing rib is fixed on the polygonal plate 11. The stability between the inner connecting plate 12 and the outer connecting plate 13 is improved by the reinforcing rib, thereby improving the stability of the polygonal plate 11, the inner connecting plate 12, the outer connecting plate 13 and the side arc plate 14 during use. The reinforcing rib is connected between the two sets of screw holes on the inner connecting plate 12 and the outer connecting plate 13. There are four screw holes in each set, which are distributed in a rectangular pattern. During installation, the inner connecting plate 12 faces the direction closer to the frame, the outer connecting plate 13 faces the direction away from the frame, and the polygonal plate 11 is set horizontally.

[0021] Two connecting reinforcing plates 17 are provided between two adjacent polygonal plates 11. Each connecting reinforcing plate 17 has a set of screw holes at both ends. The two inner connecting plates 12 and the two ends of the connecting reinforcing plates 17 are fixedly connected by bolts. The two outer connecting plates 13 and the two ends of the connecting reinforcing plates 17 are also fixedly connected by bolts. The two connecting reinforcing plates 17 are staggered. During connection, as... Figure 1 and Figure 2 As shown, the connecting frame 1 contains three polygonal plates 11. When the inner connecting plate 12 and outer connecting plate 13, located at the top and bottom, are connected to the connecting reinforcement plate 17, they are installed and fixed by aligning the ends of a set of screw holes and then using bolts. When the inner connecting plate 12 and outer connecting plate 13, located between the top and bottom, are connected to the connecting reinforcement plate 17, they are fixed by aligning two screw holes and then using bolts. Through this connection method, multiple polygonal plates 11 can be fixed together, allowing the device to be installed at different heights according to the scenario of front-mounted lifting. At the same time, an inner connecting pull plate 15 is bolted between two adjacent inner connecting plates 12. The way the inner connecting pull plate 15 is connected to the inner connecting plate 12 is the same as the way the connecting reinforcement plate 17 is connected to the inner connecting plate 12. The two polygonal plates 11 are fixed together by the two connecting reinforcement plates 17 and the inner connecting pull plate 15, thereby ensuring the overall stability of the connecting frame 1 during use.

[0022] Meanwhile, a distance-extending fixing bracket 16 is fixed at both ends of the inner connecting plate 15. A set of screw holes is also opened at one end of the distance-extending fixing bracket 16. The two distance-extending fixing brackets 16 and the inner connecting plate 15 form a C-shaped structure. The ends of the distance-extending fixing brackets 16 are fixed to the outside of the frame on both sides of the front suspension by bolts. At the same time, when the distance-extending fixing bracket 16 is fixed between the frame and the frame, the distance-extending fixing bracket 16 can fix the connecting bracket 1 at a position away from the insertion. In this way, there is space between the polygonal plate 11 and the frame. A set of screw holes is also opened at both ends of the side elastic steel strip 3. The two ends of the side elastic steel strip 3 are respectively fixed to the outer connecting plate 13 at the same height in the two connecting brackets 1 by bolts. Several side elastic steel strips 3 can protect the outside of the wheel. When the side elastic steel strip 3 is installed on the two connecting brackets 1, the distance between the side elastic steel strip 3 and the wheel can be increased. When a person or object approaches the wheel, several side elastic steel strips 3 can block it in advance to prevent the person or object from approaching the wheel, thereby preventing the wheel from running over the person or object.

[0023] The rear protective component 2 includes a central plate 21. Arc-shaped rear elastic steel strips 22 are fixed to both ends of the central plate 21. A set of screw holes is also provided at the ends of the rear elastic steel strips 22. The other end of the rear elastic steel strips 22 is fixed to a side arc plate 14 at the same horizontal level by bolts. Simultaneously, an arc-shaped soft rubber pad 23 is provided on the side of the central plate 21 away from the connecting frame 1. An I-beam connecting frame 24 is provided on the side of the central plate 21 close to the connecting frame 1. The other end of the I-beam connecting frame 24 is fixed to the rear frame of the front crane frame. The I-beam connecting frame 24, the central plate 21, and the soft rubber pad 23... The pads 23 are fixed together by bolts. The I-beam connecting frame 24 supports the middle plate 21 to prevent the middle plate 21 and the two rear elastic steel bars 22 from being too long and reducing their stability. At the same time, the soft rubber pads 23 can cushion when they touch objects, reducing the degree of collision with the objects and people they come into contact with, and reducing damage to people or objects. Rubber strips can also be installed on the outer arc surface of the rear elastic steel bars 22 and the outer arc surface of the side elastic steel bars 3 to cushion the impact force and reduce damage to people or objects.

[0024] Meanwhile, the curved side elastic steel strips 3 and rear elastic steel strips 22 have the effect of guiding people or objects to both sides when they come into contact with them, avoiding the pressure of the wheels or direct frontal collision with the frame. In the event of a collision, this reduces the risk of injury to the person being hit. At the same time, the curved side elastic steel strips 3 and rear elastic steel strips 22 can guide people or objects to one side when they come into contact with them, reducing the damage caused by a frontal collision.

[0025] Meanwhile, both the side elastic steel strip 3 and the rear elastic steel strip 22 are made of elastic steel plates using a tempering process. When an object comes into contact with the side elastic steel strip 3 and the rear elastic steel strip 22, the elasticity of the side elastic steel strip 3 and the rear elastic steel strip 22 can also buffer the impact, further reducing damage to personnel or objects.

[0026] By installing four connecting frames 1 on both sides of the two rear wheels, and placing two of them at the rear and side of the front crane frame, and then using side elastic steel strips 3 to protect the rear wheels and rear protective parts 2 to protect the rear of the frame, the side elastic steel strips 3 and rear protective parts 2 are kept at a certain distance from the frame and wheels. When a person approaches the wheels or the rear of the frame, the side elastic steel strips 3 and rear protective parts 2 can make contact with the person in advance, thus blocking the person in advance and achieving the protective effect.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
