Description

Technical Field

[0001] The utility model relates to the technical field of driven pallet trucks, in particular to an electric pallet truck with an anti-collision device. Background Art

[0002] An electric pallet truck is a small storage vehicle specially used for transporting goods. It can easily realize the turnover of goods. It uses a large-capacity battery as a power source, which can enable the device to operate continuously for several hours. It is more common in product storage warehouses in various industries.

[0003] The existing Chinese patent application number is 202322082559.0, which discloses an electric pallet truck with an anti-collision device, including an electric pallet truck body, an operating handle fixedly connected to the upper surface of the electric pallet truck body, a group of control buttons fixedly connected to the upper surface of the electric pallet truck body, and a group of anti-collision edge strips fixedly connected to the front and back of the electric pallet truck body. Through the reflective stickers and anti-collision edge strips, reflective warnings can be given to staff to prevent non-operating personnel from approaching the electric pallet truck body, and the electric pallet truck body can be protected from side collisions, which is convenient for the safe operation of the electric pallet truck body. Through the provided telescopic slots, buffer springs, limit holes, limit rods and anti-collision plates , which can provide anti-collision protection for the electric pallet truck body when inserting and removing goods, effectively avoid damage to the goods, and facilitate the effective and safe use of the electric pallet truck body. However, the device still lacks a protection structure for the two front side guard arms. Because the guard arms are relatively long as a whole, the operator standing at the rear cannot accurately judge the position of the front end of the guard arms when controlling the movement of the vehicle body, which makes it easy for the front end of the guard arms to hit the wall. Especially when the guard arms are inserted into the bottom of the goods, if the overall length of the goods is shorter than the guard arms, and the back side of the goods is close to the wall, due to the obstruction of the line of sight by the goods, it is difficult for the operator to control the depth of the guard arms inserted into the bottom of the goods, which can easily cause the front end of the guard arms to directly hit the wall, thereby damaging the guard arms and the vehicle body, causing certain economic losses.

[0004] Therefore, in view of the problem that the device in the above-mentioned reference patent lacks a protective structure for the two front guard arms, when the operator controls the mobile vehicle body to use the guard arms to insert the bottom of the cargo, he is blocked by his line of sight and cannot accurately judge the position of the front end of the guard arm. It is difficult to control the depth of the guard arm inserted into the bottom of the cargo, and it is easy for the front end of the guard arm to hit the wall, causing damage to the guard arm and the vehicle body, thereby causing certain economic losses. An electric pallet truck with an anti-collision device can be designed. The contact plate is compressed by spring 2 to buffer the squeezing force on the guard arm body. At the same time, the contact plate pushes the movable plate to move toward the vehicle body, and the push column pushes the press plate to trigger the press switch. The control module box controls the sound alarm to sound an alarm to remind the operator to stop moving immediately, so as to assist the operator in controlling the insertion depth of the guard arm body and avoid a head-on collision between the guard arm body and the wall.

[0024] See also Figure 1-Figure 4 In this embodiment, a plurality of springs 2 15 are fixedly connected at equal intervals to the outward end of the arm guard body 2. The end of each spring 2 15 away from the arm guard body 2 is fixedly connected to a protective plate 16. When an external object hits the side of the arm guard body 2, it is first blocked by the protective plate 16, and the spring 2 15 completes the buffering and unloading, thereby further protecting the arm guard body 2. The front and rear ends of the protective plate 16 are symmetrically connected with fixed rods 17. The two fixed rods 17 are fixedly connected to the surface of the arm guard body 2 at one end facing the spring 2 15. The two fixing rods 17 are fixedly connected to the limit plate 18 at one end away from the spring 2 15.

The protective rubber pads 19 provide anti-collision protection for the vehicle body 1. When the cargo is placed on the rear side of the upper end of the guard arm body 2, the anti-slip grooves 20 play an anti-slip role.

[0025] During operation, the operator controls the vehicle body 1 to move so that the two arm guard bodies 2 are inserted into the bottom of the cargo. The contact plate 5 at the front end of the arm guard body 2 will collide with the wall first. At this time, the spring 2 15 is compressed, effectively buffering the squeezing force of the contact plate 5 on the arm guard body 2. When the contact plate 5 is close to the surface of the arm guard body 2, the contact plate 5 pushes the movable plates 6 on both sides to move toward the vehicle body 1.

The cargo is placed on the upper rear side of the guard arm body 2, and the anti-slip groove 20 plays an anti-slip role. When the device moves, the protective rubber pad 19 provides anti-collision protection for the vehicle body 1, and the protective plate 16 and the spring 2 15 further provide anti-collision protection for the guard arm body 2.

[0026] Through the above steps, the operator controls the vehicle body 1 to move so that the two arm guard bodies 2 are inserted into the bottom of the cargo. The contact plate 5 at the front end of the arm guard body 2 will collide with the wall first. At this time, the spring 2 15 is compressed, effectively buffering the squeezing force of the contact plate 5 on the arm guard body 2. At the same time, the contact plate 5 pushes the movable plates 6 on both sides to move toward the vehicle body 1. The movable plates 6 on the outer side push the push column 7 to move. When the appropriate distance is reached, the push column 7 will push the pressing plate 8 to contact and press the push switch 11 provided on the control module box 10, thereby triggering the alarm. The control module box 10 controls the sound alarm 9 to sound, reminding the operator that the arm guard body 2 is now When the front end of the vehicle is close to the wall, it should stop moving immediately and assist the operator to control the depth of the guard arm body 2 inserted into the bottom of the cargo to avoid a head-on collision between the guard arm body 2 and the wall, thereby avoiding damage to the guard arm body 2 and the vehicle body 1, and avoiding economic losses caused by damage to the equipment. This is to solve the problem that the device in the reference patent lacks a protective structure for the two front guard arms. When the operator controls the moving vehicle body to use the guard arm to insert the bottom of the cargo, the operator is blocked by the line of sight and cannot accurately judge the position of the front end of the guard arm. It is difficult to control the depth of the guard arm inserted into the bottom of the cargo, which easily causes the front end of the guard arm to hit the wall, causing damage to the guard arm and the vehicle body, thereby causing certain economic losses.
