Description

Technical Field

[0001] The utility model relates to the technical field of forklifts, in particular to an anti-wear string rod of a forklift. Background Art

[0002] Forklifts are commonly used industrial transport vehicles for loading, unloading, stacking, and short-distance transportation of goods. They are typically equipped with a pair of forks to hold and support goods placed on pallets. The forklift then lifts, tilts, and other movements to perform stacking and loading operations. Currently, in fixed locations such as workshops and warehouses, AGV forklifts are often used to autonomously navigate warehouses or production lines, completing cargo handling and stacking tasks.

[0003] Conventional forks are not convenient for handling cylindrical cargo such as steel coils and wire coils. For example, when the fork is inserted into the center hole of the cylindrical cargo, the edge of the fork comes into contact with the round edge of the circular cross-section cargo, which can easily damage the surface of the cargo, affecting the transportation quality of the cargo and reducing the operation efficiency. Therefore, most people currently use skewers instead of forks to transport cylindrical cargo. However, because cylindrical cargo is generally long and heavy, the skewers will inevitably wear out during use. Severe wear can lead to insufficient support force of the skewers, resulting in the risk of cargo falling. In addition, when the AGV forklift is in operation, the cargo will tend to tilt and squeeze toward the fork frame, which can easily cause the edges of the cylindrical cargo to be squeezed and deformed, affecting the quality of the cargo. Utility Model Content

[0004] The purpose of the utility model is to provide a forklift anti-wear string rod, which reduces the wear on the string rod surface during the transportation of goods and avoids problems such as edge deformation caused by backward tilting and squeezing of goods.

[0005] The specific technical solutions of the utility model are as follows:

[0006] A forklift anti-wear string rod includes a rod body and a back plate. The rod body is vertically installed at the center of the back plate. The outer periphery of the rod body is provided with a rod body sheath. The top end of the back plate is installed with a support plate. The support plate is fixed with a load-in-place switch. The load-in-place switch and the back plate are located on the same vertical plane.

[0007] In a further solution, the rod body sheath includes a front end sheath, a middle sheath and a rear end sheath which are connected in sequence, and the middle sheath includes at least two sheath bodies.

[0008] In a further solution, a backboard sheath is installed on the outer surface of the backboard.

[0009] In a further solution, the load-in-place switch includes a sensor, a mounting plate and a sensing plate; the mounting plate includes a horizontal fixing plate and a vertical fixing plate fixed to each other as a whole, and the horizontal fixing plate is fixed to the top of the support plate; the inner wall of the vertical fixing plate is installed with a sensing plate, the sensor is connected to the sensing plate, and the bottom end of the vertical fixing plate extends to the outer wall of the back plate and is fixed.

[0010] In a further solution, an upper hook, a lower hook and a limit block are fixedly provided on the side wall of the back plate on the other side of the rod body; and a mounting hole for mounting the rod body is opened at the center of the back plate.

[0011] The utility model provides a rod body sheath made of rubber material on the rod body, which can effectively prevent the rod body from being worn by the goods during the transportation of the goods, and protect the surface quality of the goods and the rod body.

[0012] The utility model provides a rod body sheath with a segmented structure, which is sequentially sleeved on the rod body, thereby avoiding the situation where the rod body sheath needs to be replaced as a whole due to local damage, reducing the use cost of the rod body sheath and the service life of the rod body.

[0013] This application installs a load-in-place switch above the back panel to prevent the cargo on the pole from sliding backward and being squeezed and deformed or causing safety risks.

[0014] The induction plate in the load-in-place switch in the present application is a rectangular structure, which can be adapted to carry cylindrical goods of different radial sizes and has good versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0028] In this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0029] See Figure 1-5 This embodiment provides a forklift anti-wear string rod, including a rod body 11 and a back plate 12. The rod body 11 is vertically installed at the center of the back plate 12. The outer periphery of the rod body 11 is provided with a rod body sheath 2. The top of the back plate 12 is installed with a support plate 13. The support plate 13 is fixed with a load in place switch 3. The load in place switch 3 and the back plate 12 are located on the same vertical plane.

[0030] In this embodiment, a rod body sheath 2 is provided on the outer periphery of the rod body 11. The rod body sheath 2 in this application is made of rubber. While protecting the surface of the rod body from wear, it also increases the friction between the rod body and the cylindrical cargo 8, reducing the risk of the cylindrical cargo 8 slipping.

[0031] The present application installs a load-in-place switch 3 above the backplate 12. When the cylindrical cargo 8 is loaded and operated by the rod body 11, if the cylindrical cargo 8 moves backward on the rod body 11 and its rear end contacts the load-in-place switch 3, the sensor in the load-in-place switch sends a signal to the controller of the AGV forklift. The controller outputs a signal to stop the AGV forklift, thus providing safety protection. In addition, the load-in-place switch 3 in the present application has a rectangular structure, in which the height of the sensor plate 31 can adapt to cylindrical cargo of different radial sizes, thereby improving the versatility of the string rod.

[0032] In a further solution, the rod body sheath 2 includes a front end sheath, a middle sheath and a rear end sheath which are connected in sequence, and the middle sheath includes three sheath bodies.

[0033] The front end sheath, the rear end sheath and the sheath body are all made of rubber. Figure 1 As shown, the rod body sheath 2 in this application is composed of five rubber sleeves, each of which is bolted to the rod body 11. If the rod body sheath 2 is partially damaged, only the damaged rubber sleeve needs to be replaced, and normal use can be resumed, reducing the cost of the sheath. Similarly, a backplate sheath 21 is installed on the outer surface of the backplate 12 to protect the outer surface from wear by the cylindrical cargo 8.

[0034] The load position switch 3 in this application includes a sensor, a mounting plate 32 and a sensing plate 31; the mounting plate 32 includes a horizontal fixing plate and a vertical fixing plate fixed to each other as a whole, the horizontal fixing plate is fixed to the top of the support plate 13; the sensing plate 31 is installed on the inner side wall of the vertical fixing plate, the sensor is connected to the sensing plate 31, and the bottom end of the vertical fixing plate extends to the outer side wall of the back plate 12 and is fixed. Figure 2 As shown, the outer wall of the back plate 12 is provided with a groove that precisely accommodates the bottom end of the vertical fixing plate, thereby placing the outer walls of the two plates on the same vertical plane. The sensing plate 31 is connected to a sensor, whose wiring harness is connected to the controller signal on the AGV forklift. When the sensor detects cargo, it sends a signal to the AGV forklift controller, which then outputs a signal to stop the AGV forklift. This allows manual adjustment of the position of the cylindrical cargo 8, preventing wear on the rear end of the cylindrical cargo 8 and providing safety protection.

[0035] like Figure 5 As shown, the back plate 12 is fixed to the side wall on the other side of the rod body 11 with an upper hook 6, a lower hook 5, and a stop block 4. The back plate 12 is mounted on the mast of the AGV forklift via the upper hook 6 and the lower hook 5. The stop block 4 is used to support the support plate 13 and strengthen its support strength. The center of the back plate 12 is provided with a mounting hole 7 for mounting the rod body 11. The end of the rod body 11 is inserted into the mounting hole 7 and welded to the back plate 12. A reinforcement seat is fixed to the outer periphery of the mounting hole 7 on one side of the rod body 11 to enhance the mounting strength of the rod body 11.

[0036] The string rod of the utility model is installed on the door frame of the AGV forklift through the upper hook 6 and the lower hook 5. Figure 6As shown. When in use, the front end of the string rod is inserted into the center hole of the cylindrical cargo 8 to be transported. The rod body sheath 2 sleeved on the outer periphery of the rod body 11 avoids direct contact between the cylindrical cargo 8 and the surface of the rod body 11, which not only protects the surface of the rod body and the surface of the cargo at the same time; it also increases the friction between it and the cylindrical cargo 8, reducing the risk of the cylindrical cargo 8 sliding on the rod body 11. When the rod body sheath 2 is partially worn, it is only necessary to replace the damaged local rubber sheath, reducing the cost of using the rod body sheath. When the cylindrical cargo 8 slides backward on the rod body and contacts the load in place switch 3, the sensor in the load in place switch 3 sends a signal to the control in the AGV forklift, causing it to stop transportation, thereby playing a role in safety protection.

[0037] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application are within the scope of protection of the pending claims of the present application.
