Technical Field
[0001] The utility model relates to the technical field of logistics unloading, in particular to an anti-tilt manual forklift. Background Art
[0002] When unloading, the unloading personnel should choose the unloading tools and methods according to the weight and size of the goods. For fragile and easily damaged goods, lifting equipment should be used as much as possible; for goods that need to avoid vibration, such as electronic products, they need to be classified and packaged, and protected with shock-absorbing materials. The unloading site should be flat, reliable, wide, and unobstructed, preferably with cement or asphalt flooring. Before the vehicle stops, you should check whether the ground of the unloading site is flat to prevent accidents during the unloading process.
[0003] Forklifts are industrial handling vehicles, which refer to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. They are often used for the transportation of large objects in storage, usually driven by fuel engines or batteries. Among them, manual forklifts are high-lifting loading and unloading and short-distance transportation vehicles. Because they do not generate sparks and electromagnetic fields, they are particularly suitable for loading and unloading of cars and loading and unloading of flammable, explosive and fire-prohibited items in workshops, warehouses, docks, stations, freight yards, etc. This product has the characteristics of balanced lifting, flexible rotation and easy operation.
[0004] In the process of realizing the present invention, the inventors found that the prior art had the following problems: 1. When existing manual forklifts are used to transport goods of a certain height, manual pressure is often required to raise the height of the fork frame, which is labor-intensive and has a limited lifting height; 2. When existing manual forklifts need to transfer and unload stacked goods, they often cannot ensure that the goods do not tip over during the transportation process, resulting in loss of the goods. Utility Model Content
[0005] The purpose of the utility model is to provide an anti-tilt manual forklift to solve the problem mentioned in the above background technology that when the existing manual forklift is used to transport goods of a certain height, it is often necessary to manually press to raise the height of the fork frame, which consumes energy and the lifting height is also limited. In addition, when the existing manual forklift needs to transfer and unload the stacked goods, it is often unable to ensure that the goods will not tip over during the transportation process, thereby causing the loss of the goods. To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an anti-tilt manual forklift comprises a base, the front end of the base is fixedly connected to a bottom plate, a fork frame is provided just above the bottom plate, the fork frame is slidably connected to the inner walls on the left and right sides of the frame, the inner wall of the frame is rotatably connected to a screw, the bottom end of the screw is inserted into the middle part of the driven gear, the top of the base is located at the rear side of the frame and a driving motor is fixedly installed, the outer wall of the driving motor output end is fixedly connected to the middle part of the driving gear, the top of the base is fixedly installed with a transverse slide groove, the inner wall of the transverse slide groove is fixedly connected to an anti-tilt device, the top center of the anti-tilt device is fixedly connected to the top of a telescopic rod, the bottom end of the telescopic rod is fixedly connected to the middle part of the top of the base, and the end of the base is fixedly connected to a handle.
[0006] Further preferably, a large universal wheel is fixedly mounted on the bottom of the base, and a pair of small universal wheels is fixedly mounted on the bottom of the bottom plate, and a groove is provided on the surface of the bottom plate, and the inner diameter of the groove is just large enough to accommodate the fork frame.
[0007] Further preferably, vertical sliding grooves are provided on the inner walls on both sides of the left and right sides of the frame, and the frame is slidably connected with the fork frame through the vertical sliding grooves.
[0008] Further preferably, the top of the fork frame extends to the inside of the frame, and the screw rod vertically penetrates the inner wall of the frame and also vertically penetrates the top of the fork frame, so that the fork frame and the screw rod form a threaded connection.
[0009] Further preferably, the driving gear and the driven gear are meshed with each other.
[0010] Further preferably, a telescopic bottom rod is provided at the bottom of the anti-tilt device, and the telescopic bottom rod is fixedly connected to the transverse slide groove, and the left and right ends of the telescopic bottom rod are fixedly connected with telescopic guardrails, and at the same time, the top of the telescopic guardrail is fixedly connected to the telescopic rod.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] In the utility model, when the driving motor is started and begins to rotate, it will drive the driving gear and the driven gear to rotate together. Because a screw rod is vertically penetrated through the middle of the driven gear, the screw rod also rotates continuously. In this process, the top of the fork frame is threadedly connected with the screw rod, and the rotating screw rod can adjust the rise of the fork frame. The goods mounted on the surface of the fork frame can rely on the slider of the fork frame to rise to the specified position along the inner wall of the vertical slide groove, so that unloading and placement can be easily carried out. When it is necessary to transport again, it is only necessary to control the driving motor to rotate in the opposite direction, so that the screw rod can also rotate in the opposite direction, thereby driving the fork frame to descend to the original position, and then unloading can continue.
[0013] In the utility model, both ends of the telescopic bottom rod in the anti-tilt device can be telescoped in length, and the left and right ends of the telescopic bottom rod are fixedly connected with telescopic guardrails, so the telescopic guardrails on both sides can adjust the spacing according to the actual width of the goods, so as to tightly clamp the goods during transportation. When the goods need to be stacked and exceed the original height of the telescopic guardrails, the telescopic guardrails on both sides can be pulled up to the same height as the stacked goods by starting the telescopic rod fixedly connected to the top of the telescopic guardrails, thereby providing more comprehensive anti-dumping protection for the transportation process of high-rise goods.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figures 1 to 4 The utility model provides a technical solution: an anti-tilt manual forklift, comprising a base 1, a bottom plate 2 is fixedly connected to the front end of the base 1, a fork frame 3 is arranged directly above the bottom plate 2, the fork frame 3 is slidably connected to the inner walls of the left and right sides of the frame 4, the inner wall of the frame 4 is rotatably connected to a screw rod 5, the bottom end of the screw rod 5 is inserted into the middle of a driven gear 6, the top of the base 1 is located at the rear side of the frame 4 and a driving motor 7 is fixedly installed, the outer wall of the output end of the driving motor 7 is fixedly connected to the middle of a driving gear 8, a transverse slide groove 9 is fixedly installed on the top of the base 1, an anti-tilt device 10 is fixedly connected to the inner wall of the transverse slide groove 9, the top center of the anti-tilt device 10 is fixedly connected to the top of a telescopic rod 11, the bottom end of the telescopic rod 11 is fixedly connected to the middle of the top of the base 1, and the end of the base 1 is fixedly connected to a handle 12.
[0021] In this embodiment, Figure 1 and Figure 3 As shown, a universal large wheel 101 is fixedly installed at the bottom of the base 1, and a pair of universal small wheels 201 are fixedly installed at the bottom of the base plate 2, and a groove is opened on the surface of the base plate 2, and the inner diameter of the groove is just enough to accommodate the fork frame 3; it should be noted that when the operator uses the manual forklift, he only needs to manually hold the handle 12 and apply a force in a fixed direction to it, and the universal large wheel 101 fixedly installed at the bottom of the base 1 will roll in the specified direction, thereby driving the universal small wheel 201 fixedly installed at the bottom of the base plate 2 to roll in the same direction. Therefore, the direction of travel of the entire forklift can be easily controlled by controlling the pulling direction of the handle 12. At the same time, after the forklift completes the unloading work, by starting the drive motor 7 to rotate and drive the driving gear 8 and the driven gear 6, the fork frame 3 can be controlled to spirally descend along the screw rod 5 until the fork frame 3 is placed in the groove opened on the surface of the base plate 2, thereby ensuring that the fork frame 3 body can be protected by the base plate 2 when not in use.
[0022] In this embodiment, Figure 4As shown, vertical slide grooves 401 are provided on the inner walls on the left and right sides of the frame 4, and the frame 4 is slidably connected with the fork frame 3 through the vertical slide grooves 401; it should be noted that the fork frame 3 is in a "Z" shape as a whole, and two sliders are provided on the left and right sides of the top of the fork frame 3, and the sliders can be placed in the vertical slide grooves 401 provided on the inner walls on the left and right sides of the frame 4, so that the entire fork frame 3 is slidably connected with the frame 4. When using a forklift to unload and transport, it is necessary to start the drive motor 7 first, because the output end of the drive motor 7 vertically penetrates the middle of the driving gear 8, and the driving gear 8 and the driven gear 6 are meshed with each other. Therefore, when the output end of the driving motor 7 is driven to start rotating, the driving gear 8 will be driven to start rotating together, and the driven gear 6 meshing with the driving gear 8 will also rotate together. Because the middle part of the driven gear 6 is vertically penetrated by the screw rod 5, the rotating driven gear 6 will drive the screw rod 5 to rotate continuously. In this process, the top of the fork frame 3 is threadedly connected with the screw rod 5, and the rotating screw rod 5 can adjust the lifting and lowering of the fork frame 3. When goods are placed on the surface of the fork frame 3, the fork frame 3 can rely on the slider to follow the inner wall of the vertical slide groove 401 to make the goods rise or fall to the appropriate position, so that unloading and placement can be easily carried out.
[0023] In this embodiment, Figure 2 As shown, the top of the fork frame 3 extends to the inside of the frame 4, and the screw rod 5 vertically penetrates the inner wall of the frame 4 and also vertically penetrates the top of the fork frame 3, so that the fork frame 3 and the screw rod 5 are threadedly connected; it should be noted that because the screw rod 5 vertically penetrates the inner wall of the frame 4 and also vertically penetrates the top of the fork frame 3, when the drive motor 7 is started, the output end of the drive motor 7 starts to rotate and drives the driving gear 8 to start rotating together, and the driven gear 6 meshing with the driving gear 8 also rotates together, and because the screw rod 5 vertically penetrates the middle part of the driven gear 6, it will be driven to rotate continuously at the same time, at this time, the fork frame 3 threadedly connected with the screw rod 5 is controlled to rise, and the goods mounted on the surface of the fork frame 3 will also be brought up together, this operation can transport the goods to a position at a specified height to complete unloading, and when it is necessary to transport again, it is only necessary to control the drive motor 7 to rotate in the opposite direction, so that the screw rod 5 can also rotate in the opposite direction, thereby driving the fork frame 3 to descend to the original position and continue unloading.
[0024] In this embodiment, Figure 2 and Figure 4As shown, the driving gear 8 and the driven gear 6 are meshed with each other; it should be noted that a driving motor 7 is vertically penetrated in the middle of the driving gear 8, and a screw rod 5 is vertically penetrated in the middle of the driven gear 6, and both gears are installed on the top of the base 1. When the driving motor 7 is started, its output end begins to rotate, thereby driving the driving gear 8 fixedly connected to the output end to also start to rotate. Because the driving gear 8 and the driven gear 6 are meshed with each other, when the driving gear 8 rotates, the driven gear 6 also starts to rotate. Because the middle of the driven gear 6 is vertically penetrated by the screw rod 5, the screw rod 5 will rotate together with the gear rotation. During this period, the fork frame 3 threadedly connected with the screw rod 5 will rise along the thread provided by the screw rod 5, and will lift the goods mounted on the surface of the fork frame 3 to a designated height. When the driving motor 7 rotates in the reverse direction, the driving gear 8 and the driven gear 6 are also meshed in the reverse direction, driving the screw rod 5 to rotate in the reverse direction, thereby controlling the fork frame 3 to spirally descend and unload again.
[0025] In this embodiment, Figure 3 As shown, a telescopic bottom rod 1001 is provided at the bottom of the anti-tilt device 10, and the telescopic bottom rod 1001 is fixedly connected to the transverse slide groove 9, and the left and right ends of the telescopic bottom rod 1001 are fixedly connected with telescopic guardrails 1002, and at the same time, the top of the telescopic guardrail 1002 is fixedly connected to the telescopic rod 11; it should be noted that when the operator is unloading, the forklift is required to move the goods to the placement place first. During the transportation process, the goods may fall over due to uneven road surface and unstable stacking of goods. Therefore, an anti-tilt device 10 is required to be arranged on the forklift itself to prevent this phenomenon from happening. A transverse slide groove 9 is provided on the top of the forklift base 1, and the transverse slide groove 9 is fixedly connected to the anti-tilt device 10. The telescopic bottom rod 1001 provided at the bottom of the inclined device 10 constitutes a fixed connection, and the two ends of the telescopic bottom rod 1001 can be telescoped in length, and the telescopic guardrails 1002 are fixedly connected to the left and right ends of the telescopic bottom rod 1001. Therefore, the telescopic guardrails 1002 on both sides can adjust the spacing according to the actual width of the goods, so as to tightly clamp the goods during transportation. Because the goods need to be stacked and exceed the original height of the telescopic guardrails 1002, the telescopic guardrails 1002 on both sides can be pulled up to the same height as the stacked goods by starting the telescopic rod 11 fixedly connected to the top of the telescopic guardrails 1002, thereby providing more comprehensive anti-dumping protection for the transportation process of high-rise goods.
[0026] The use method and advantages of the utility model: When the anti-tilt manual forklift is in use, the working process is as follows:
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first the operator holds the handle 12 and drives the forklift to the place where the goods need to be unloaded. When the drive motor 7 is started, the output end of the drive motor 7 rotates and drives the driving gear 8 to start rotating. At the same time, the driven gear 6 meshing with the driving gear 8 also rotates together. At this time, the screw 5 vertically passing through the middle of the driven gear 6 will be driven to rotate continuously at the same time, and control the fork frame 3 threadedly connected to it to spirally rise to the same height as the goods, insert the fork frame 3 into the bottom of the goods, and set the goods on the surface of the fork frame 3, and then adjust the spacing of the telescopic guardrail 1002 according to the actual width of the goods, so as to clamp the goods tightly, and then adjust the spacing of the telescopic guardrail 1002 according to the actual width of the goods. The telescopic guardrail 1002 on both sides is pulled up to the same height as the stacked goods by starting the telescopic rod 11 fixedly connected to the top of the telescopic guardrail 1002, thereby providing more comprehensive anti-dumping protection for the transportation process of high-rise goods, and then the forklift is pulled again, and the direction of travel is controlled by the universal large wheel 101 and the universal small wheel 201 installed at the bottom of the base 1 and the bottom plate 2, and the forklift is pulled to the unloading place. After arriving at the destination, the motor 7 is driven again to rotate in the opposite direction. At the same time, the driving gear 8 and the driven gear 6 are also meshed in the opposite direction, thereby driving the screw 5 to rotate in the opposite direction, and then controlling the fork frame 3 to spirally descend to the specified height, place the goods, and complete the unloading.
