DETAILED DESCRIPTION

[0022] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0023] Example

[0024] The anti-collision device for a material handling vehicle described in this embodiment is as follows: Figures 1 to 6 As shown, it includes two mounting plates 1 distributed on the left and right, and the two mounting plates 1 are respectively installed on the head and tail of the material handling vehicle. During installation, the mounting plates 1 can be directly fixed to the head and tail of the material handling vehicle by screws. During production, threaded holes are opened at the head and tail of the material handling vehicle to facilitate the installation of the mounting plates 1, which will not affect the normal use of the material handling vehicle.

[0025] like Figure 3 As shown, the outer side of the mounting plate 1 is provided with an independent anti-collision bar 4. In this embodiment, the inner side and the outer side refer to the side away from the material handling vehicle as the outer side, and the side close to the material handling vehicle as the inner side. The two ends of the anti-collision bar 4 are in an arc-shaped structure that is bent inwardly, like the bumpers of some vehicles. The arc-shaped arrangement of the two ends of the anti-collision bar 4 can effectively protect the corner part of the material handling vehicle, and the arc-shaped structure can also play a role in unloading some forces.

[0026] like Figure 2 and Figure 5 As shown, the outer side wall of the mounting plate 1 is provided with a movable plate 7 limited to forward and backward sliding; two dovetail grooves distributed up and down are opened on the outer side wall of the mounting plate 1, and two sliders 2 distributed up and down and slidingly matched with the dovetail grooves for forward and backward sliding are fixed on the inner side wall of the movable plate 7, and the cross-section of the slider 2 is dovetail-shaped; when in use, the movable plate 7 and the mounting plate 1 cooperate with the dovetail groove and the slider 2 so that the movable plate 7 can only slide forward and backward.

[0027] like Figure 3As shown, two springs 6 are arranged between the movable plate 7 and the bumper bar 4, one end of the spring 6 is fixed to the outer wall of the movable plate 7, and the other end is fixed to the inner wall of the bumper bar 4. This section as a whole constitutes a buffer assembly for buffering impact. When installed, the two springs 6 are located between the two folding plates. When the bumper bar 4 is hit, the spring 6 can play a role of shock absorption and buffering to avoid damage to the material handling vehicle or damage to the goods carried by the material handling vehicle; in addition, the buffer assembly also includes a spring sheet.

[0028] like Figure 3 and Figure 5 As shown, at least two groups of folding plates are arranged between the movable plate 7 and the anti-collision bar 4, and the two ends of all the folding plates are hinged to the movable plate 7 and the anti-collision bar 4 respectively; the folding plates of this embodiment are two groups distributed front and back; when in use, when the anti-collision bar 4 collides, the folding plates fold while the spring 6 is compressed to ensure the stability of the anti-collision bar 4; when the spring 6 is in a natural state, the two groups of folding plates are in a pre-folding state to one side of the spring 6 at the same time, that is, a semi-folded state; the folding plate includes a first hinge plate 10, one end of the first hinge plate 10 is hinged to the inner side wall of the anti-collision bar 4, and the other end thereof is hinged to a second hinge plate 11, and the other end of the second hinge plate 11 is hinged to the outer side wall of the movable plate 7; the specific hinge structure can be referred to Figure 3 shown.

[0029] like Figure 3 and Figure 4As shown, the movable plate 7 is located in the middle of the mounting plate 1. Two tension springs 3 are arranged between the movable plate 7 and the mounting plate 1, and two first fixing nails 12 are fixed on the top of the movable plate 7 and are distributed in the front and back directions. The two first fixing nails 12 are respectively located at the front and back ends of the movable plate 7; two second fixing nails 13 are fixed on the top of the mounting plate 1 and are distributed in the front and back directions. The two second fixing nails 13 are both located in the middle of the mounting plate 1; the two ends of the tension spring 3 located on the rear side are respectively connected to the first fixing nail 12 and the second fixing nail 13 located on the rear side, and the two ends of the tension spring 3 located on the front side are respectively connected to the first fixing nail 12 and the second fixing nail 13 located on the front side. When the movable plate 7 is reset, the movable plate 7 is reset under the action of the front tension spring 3, and vice versa. In the actual production process, it is not easy for the two tension springs 3 to reach a balance point to realize the reset of the movable plate 7. Therefore, during production, the second fixing nail 13 at the front side and the first fixing nail 12 at the front side can be aligned horizontally with each other, and the second fixing nail 13 at the rear side can be aligned horizontally with each other. The first fixing nail 12 is flush with the left and right sides, and the two ends of the tension spring 3 located on the front side are respectively connected to the first fixing nail 12 and the second fixing nail 13 located on the front side, and the two ends of the tension spring 3 located on the rear side are respectively connected to the first fixing nail 12 and the second fixing nail 13 located on the rear side. When the movable plate 7 is located in the middle of the mounting plate 1, that is, the movable plate 7 is in the initial state, the two tension springs 3 are in a natural state (contracted state). At this time, no matter whether the movable plate 7 slides forward or backward, the two tension springs 3 will be stretched and produce a resetting tension. When the two tension springs 3 are retracted to the natural state, the movable plate 7 is reset; during installation, since the mounting plate 1 and the movable plate 7 are in contact with each other, when the first fixing nail 12 and the second fixing nail 13 are flush with each other, the distance between the two is small, which is not convenient for the installation of the tension spring 3. Therefore, the extension plate can be fixed on the movable plate 7, and the first fixing nail 12 can be fixed on the extension plate to increase the distance between the first fixing nail 12 and the second fixing nail 13, so as to facilitate the installation of the tension spring 3. The purpose of the movable plate 7 moving forward and backward is mainly to enable the anti-collision bar 4 to move forward and backward to unload the impact force in the corresponding direction.

[0030] like Figure 3 , Figure 4 and Figure 6As shown, two baffles 9 are arranged between the two anti-collision bars 4, and the two ends of the front baffle 9 are connected to the front ends of the two anti-collision bars 4, and the two ends of the rear baffle 9 are connected to the rear ends of the two anti-collision bars 4. When in use, the material handling vehicle is located between the two baffles 9. In order for the material handling vehicle not to occupy too much width space, and at the same time, the baffle 9 needs to have the ability to prevent lateral collision, the spacing between the baffle 9 and the material handling vehicle is selected to be between 40mm and 80mm. If it is too small, the anti-collision effect will be poor, and if it is too large, it will occupy too much width space. Slots are provided at the front and rear ends of the anti-collision bar 4, and the two ends of the baffle 9 are connected to the anti-collision bar 4 through the slots. When in use, the two ends of the baffle 9 are directly inserted into the slots from top to bottom to realize the connection between the two ends of the baffle 9 and the anti-collision bar 4, which is convenient for disassembly. During production, the baffle 9 can be made of wood, which is light and elastic, and has low production cost. The other two anti-collision bars 4 and two baffles 9 can be disassembled separately, which is convenient for disassembly and assembly, maintenance, and partial parts can be replaced separately if damaged.

[0031] like Figure 5 As shown, an anti-collision strip 5 is arranged on the outer wall of the anti-collision bar 4. The anti-collision strip 5 is a prior art. The main function of the anti-collision strip 5 is to protect the surface of the object from damage caused by collision and scratching. They are usually made of soft and elastic materials, can absorb impact force, reduce damage to the object itself, and can reduce the noise generated when the object collides.

[0032] During actual use, the material handling vehicle is surrounded by two anti-collision bars 4 and two baffles 9. When the head or tail of the material handling vehicle collides, the anti-collision bars 4 at the head and tail are linked to each other to play a better role in shock absorption and collision prevention. For example, when the anti-collision bar 4 at the head is hit, the spring 6 there contracts to reduce shock. At the same time, the force is transmitted to the anti-collision bar 4 at the tail through the baffle 9, and the spring 6 at the tail is stretched to unload the force. The front and rear are linked to each other to better protect the material handling vehicle. In addition, when the side of the material handling vehicle collides and hits the baffle 9, the force is specifically delivered to the anti-collision bars 4 at the head and tail, and the two anti-collision bars 4 move to the side at the same time to unload the impact to a certain extent, which can prevent the material handling vehicle from being hit and derailed to a certain extent. Through multi-directional protection, the material handling vehicle has a better anti-collision effect.
