[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figs. 1-5As shown, a forklift protective device includes a protective cover 2 and a monitoring component 3. The protective cover 2 is detachably mounted on the housing 11 at the rear of the forklift 1, covering the outside of the two wheels 12 at the rear of the forklift 1. The monitoring component 3 is fixedly mounted on the housing 11 at the rear of the forklift 1, located above the protective cover 2. The monitoring component 3 includes a radar probe 31, a sensor 32, an alarm light 33, and a radar host 34. The radar probe 31, sensor 32, and alarm light 33 are fixedly mounted on the housing 11 at the rear of the forklift 1 and located above the protective cover 2. The radar host 34 is fixedly mounted in the cab of the forklift 1. The radar probe 31 and radar host 34 are electrically connected, and the sensor 32 is electrically connected to the alarm light 33. The structure of the forklift 1 is prior art and will not be described in detail here. The structure and interaction method of the radar probe 31 and radar host 34, as well as the structure and interaction method of the sensor 32 and alarm light 33, are prior art and will not be described in detail here. Here is a brief explanation: Sensor 32 monitors the position of obstacles outside the forklift 1 in real time and feeds the data back to the on-board computer of the forklift 1. When sensor 32 detects an abnormality, the on-board computer of the forklift 1 receives an error signal and immediately activates the corresponding alarm light 33. Sensor 32 and alarm light 33 are electrically connected to achieve monitoring.

[0022] When the driver operates the forklift 1, the two rear wheels 12 of the forklift 1 need to be turned. If the driver is negligent, the two rear wheels 12 of the forklift 1 may hit other equipment or personnel.

[0023] In this embodiment, the protective device protects the two wheels 12 at the rear of the forklift 1. First, the protective cover 2 is fixed on the housing 11 at the rear of the forklift 1. At this time, the protective cover 2 covers the outside of the two wheels 12 at the rear of the forklift 1. The protective cover 2 prevents the wheels 12 from colliding with other equipment or personnel when turning. Moreover, when it is necessary to inspect or repair the wheels 12, the protective cover 2 can be removed.

[0024] In this embodiment, a monitoring component 3 is added to the protective device. The function of the monitoring component 3 is to monitor the status of the two wheels 12 at the rear of the forklift 1 when performing steering operations. Specifically, the radar probe 31 detects the position of the forklift 1 and displays the image detected by the radar host 34 (including the display screen). When the driver operates the forklift 1, by observing the image detected by the radar host 34, he can more accurately operate the forklift 1, i.e., the wheels 12, to steer, and also avoid collisions between the protective cover 2 and other equipment or personnel, thus improving the service life of the protective cover 2. The sensor 32 is an infrared sensor. The sensor 32 is used to detect obstacles approaching the forklift 1. When the obstacle reaches the danger distance set by the sensor 32, the alarm light 33 sounds an alarm to remind the driver, which also aims to enable the driver to operate the forklift 1, i.e., the wheels 12, to steer more accurately, avoid collisions between the protective cover 2 and other equipment or personnel, and improve the service life of the protective cover 2.

[0025] The forklift safety device of this embodiment includes a protective cover 2 that prevents the wheels 12 from colliding with other equipment or personnel during steering operations. Furthermore, the protective cover 2 can be removed when the wheels 12 need inspection or maintenance. Simultaneously, when operating the forklift 1, the driver can observe the detected images on the radar host 34 and the alarm lights 32, thereby more accurately steering the forklift 1 (i.e., the wheels 12) and preventing collisions with other equipment or personnel, thus extending the service life of the protective cover 2. This safety device improves the safety performance and working efficiency of the forklift 1, thereby increasing workshop production efficiency and reducing the maintenance costs of the forklift 1.

[0026] In one possible implementation, two protective covers 2 are provided, each covering the outer side of the two wheels 12 at the rear of the forklift 1. Each protective cover 2 includes a top plate 21, a semi-circular side plate 22, and a connecting plate 23. The semi-circular side plate 22 is fixedly connected to the bottom of the top plate 21 and located on one side of the top plate 21, while the connecting plate 23 is fixedly connected to the top of the top plate 21 and located on the other side of the top plate 21. The top plate 21 is detachably mounted on the lower part of the housing 11 at the rear of the forklift 1. The top plate 21 and the semi-circular side plate 22 cover the outer side of the wheels 12 at the rear of the forklift 1, with a gap between the bottom of the semi-circular side plate 22 and the working ground. The bottom of the semi-circular side plate 22 does not contact the working ground and does not affect the movement of the forklift 1. The top plate 21, the semi-circular side plate 22, and the connecting plate 23 can be welded together. The top plate 21 is fixedly installed on the lower part of the housing 11 at the rear of the forklift 1. The top plate 21 and the semi-circular side plate 22 cover the outside of the wheels 12 at the rear of the forklift 1, thereby protecting the wheels 12. In this embodiment, the protective device protects the two wheels 12 at the rear of the forklift 1. First, the two protective covers 2 are fixed on the housing 11 at the rear of the forklift 1. At this time, the two protective covers 2 are respectively covered on the outside of the two wheels 12 at the rear of the forklift 1. The two protective covers 2 prevent the wheels 12 from colliding with other equipment or personnel when turning. Moreover, when it is necessary to inspect or repair the wheels 12, the protective covers 2 can be removed.

[0027] In one possible implementation, two radar probes 31 and three sensors 32 and alarm lights 33 are provided. Specifically, the two radar probes 31 are fixedly mounted on the upper part of the housing 11 at the rear of the forklift 1 and are respectively located above the two protective covers 2. The sensors 32 and alarm lights 33 are evenly fixedly mounted on the upper part of the housing 11 at the rear of the forklift 1, that is, there is one sensor 32 and one alarm light 33 on each side of the upper part of the housing 11 at the rear of the forklift 1, and one sensor 32 and one alarm light 33 in the middle of the upper part of the housing 11 at the rear of the forklift 1. The two radar probes 31 transmit the detected images to the radar host 34. The three sensors 32 detect the position of more obstacles, further enabling the driver to operate the forklift 1, i.e., the wheels 12, more accurately for steering, avoiding collisions between the protective covers 2 and other equipment or personnel, and improving the service life of the protective covers 2.

[0028] As one possible implementation, each of the semi-circular side plates 22 is uniformly provided with multiple observation ports along its height direction, and each of the observation ports corresponds to the wheel 12 at the rear of the forklift 1. A flexible pad 24 is fixedly provided on the outer surface of each semi-circular side plate 22. The flexible pad 24 can be bonded to the outer surface of the semi-circular side plate 22 with high-strength adhesive, and the flexible pad 24 covers other positions of the semi-circular side plate 22 except for the observation ports. The purpose of providing multiple observation ports is to facilitate observation of the condition of the wheel 12. If a problem such as insufficient air pressure is found in the wheel 12, the protective cover 2 can be removed. The flexible pad 24 allows a person to lie on the protective cover 2 to observe the condition of the wheel 12; moreover, when the driver operates the forklift 1, if improper operation causes the protective cover 2 to collide with other equipment or personnel, the flexible pad 24 acts as a buffer, minimizing hard damage and extending the service life of the protective cover 2.

[0029] As one possible implementation, multiple semi-circular reinforcing beams 25 are uniformly fixed to the inner side of each of the semi-circular side plates 22. The semi-circular reinforcing beams 25 are welded and fixed to the inner side of the semi-circular side plate 22, and each observation port is located in the middle of two adjacent semi-circular reinforcing beams 25. The purpose of setting the semi-circular reinforcing beams 25 is to enhance the rigidity of the entire semi-circular side plate 22. When the driver operates the forklift 1, if improper operation causes the protective cover 2 to collide with other equipment or personnel, the semi-circular side plate 22 will not be damaged too much and require frequent replacement even if a collision occurs, thus avoiding affecting the working efficiency of the forklift 1.

[0030] As one possible implementation, multiple flexible strips 26 are uniformly fixedly arranged below each of the semi-circular side plates 22. The top of the flexible strips 26 can be locked and fixed to the bottom of the semi-circular side plate 22 by screws and nuts. The multiple flexible strips 26 are arranged in a semi-circular shape, and the bottom of each flexible strip 26 is in contact with the working ground. When the driver operates the forklift 1, the flexible strips 26 do not affect the overall movement of the forklift 1. If there are foreign objects on the working ground, when the wheel 12 runs over a small foreign object and causes the foreign object to bounce, the flexible strips 26 can prevent the foreign object from splashing and prevent it from flying out from the gap between the bottom of the semi-circular side plate 22 and the working ground, thus preventing injury to other workers.

[0031] As one possible implementation, each of the semi-circular side plates 22 has a rubber strip 27 fixedly installed at both ends. The rubber strip 27 has a groove, and the end of the semi-circular side plate 22 is engaged in the groove, that is, the rubber strip 27 is engaged at the end of the semi-circular side plate 22. A person can assemble and disassemble the semi-circular side plate 22, i.e., the protective cover 2, by holding the rubber strip 27, thus avoiding cuts to the hands from the end of the semi-circular side plate 22, and also avoiding hard damage to foreign objects from the end of the semi-circular side plate 22.

[0032] In one possible implementation, each connecting plate 23 is uniformly provided with a plurality of first screw holes and first pin holes, and the lower part of the housing 11 at the rear of the forklift 1 is uniformly provided with a plurality of second screw holes and second pin holes. The pin passes through the first pin hole to the second pin hole, and the bolt is fixedly connected to the first screw hole and the second screw hole. By engaging the first pin hole and the second pin hole, the position of the connecting plate 23 can be quickly positioned. Then, by engaging the bolt, the first screw hole and the second screw hole, the connecting plate 23, i.e., the protective cover 2, is fixed to the lower part of the housing 11 at the rear of the forklift 1.

[0033] The embodiments described above are merely preferred embodiments of this utility model and are only used to explain this utility model. They are not intended to limit the scope of implementation of this utility model. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification.
