Description

Technical Field

[0001] The utility model relates to the technical field of forklifts, in particular to a protective device for a driver's cabin of a stand-on forklift. Background Art

[0002] 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 now widely used in ports, stations, airports, freight yards, factory workshops, warehouses, circulation centers and distribution centers, etc., for loading and unloading, stacking and short-distance transportation of palletized goods in cabins, carriages and containers.

[0003] Among them, stand-on forklifts are well used due to their smaller size and flexible operation. There is no seat in the cockpit, and the driver operates while standing, which helps provide better vision and flexibility in narrow spaces. In order to ensure the safety of the driver during operation, protective devices such as guardrails and protective nets are installed around the cockpit. These protective devices are all metal structures such as iron and steel. When the driver is driving a forklift, the knees will contact the metal structures due to frequent acceleration or braking, which reduces driving comfort and aggravates the operator's driving fatigue. In addition, since the cockpit is surrounded by heat sources such as hydraulic oil tanks, motors and oil pumps, heat will radiate as the forklift works for a long time, causing the cockpit to heat up, which will bring a bad driving experience in hot weather. Therefore, it is necessary to install protective devices in the cockpit. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a protective device for a driver's cabin of a stand-on forklift.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The protective device of the cab of a stand-on forklift includes a guardrail. A protective pad is installed on the inner wall of the guardrail located in front of the cab. A metal insert is installed on the outer periphery of the protective pad. The metal insert includes a locking cylinder embedded in the protective pad. Support plates are respectively fixed at both ends of the locking cylinder, and the support plates are located on the outside of the protective pad.

[0007] According to a further solution, an axial hole is opened at the center of the metal insert, and the protective pad is fixed to the guardrail after passing through the axial hole with bolts.

[0008] In a further embodiment, the end face diameter of the support plate is larger than the end face diameter of the locking cylinder.

[0009] In a further embodiment, a plurality of transverse convex strips are longitudinally spaced apart on the inner side wall of the protective pad.

[0010] In a further solution, the protective pad is a square structure with a U-shaped notch in the middle of the bottom end; metal inserts are respectively installed at the four corners of the protective pad and on both sides of the U-shaped notch.

[0011] In a further embodiment, the protective pad is a polyurethane foam pad.

[0012] The present application installs a protective pad on the inner wall of the guardrail located in front of the cockpit. The protective pad is a polyurethane foam pad, which has elasticity and cushioning properties, thereby effectively reducing the pressure or collision when the driver's body parts come into contact with the vehicle body while driving, and relieving driving fatigue.

[0013] The protective pad of the present application can effectively isolate the heat radiation from the hydraulic oil tank, motor and other components, avoiding the discomfort caused to the driver by the temperature rise;

[0014] The present application adopts metal inserts as the supporting members of the polyurethane foam pad, which significantly reduces the use cost compared with the use of large flat sheet metal parts fixed on the polyurethane foam pad as the supporting members.

[0015] The present application uses metal inserts as the connectors of the polyurethane foam pads. During installation, bolts are passed through the metal inserts to fix them on the guardrails, thereby avoiding the situation where the polyurethane foam pads are squeezed and deformed around the edges during fixation or the edges are pried due to the inadequate fixation due to the soft material of the polyurethane foam pads. It also avoids the problem of large deviations in the appearance and structural dimensions of the polyurethane foam pads and unstable installation due to unstable installation.

[0016] The present application provides a plurality of transverse convex strips at longitudinal intervals on the inner side wall of the protective pad, thereby increasing and thickening the contact surface, reducing the pressure when the knee contacts the pad, and effectively alleviating driving fatigue.

[0022] 2. Metal insert, 21. Left support plate, 22. Locking cylinder, 23. Right support plate. DETAILED DESCRIPTION

[0023] 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 the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0024] See also Figure 1 , 2 As shown, the protection device of the cab of a stand-on forklift includes a guardrail, and a protection pad 1 is installed on the inner wall of the guardrail located in front of the cab. A metal insert 2 is installed on the outer periphery of the protection pad 1. The metal insert 2 includes a locking cylinder 22 embedded in the protection pad 1. A left support plate 21 and a right support plate 23 are fixed at both ends of the locking cylinder 22. The left and right support plates are respectively located on the two outer sides of the protection pad 1 for supporting the protection pad 1.

[0025] The present application installs a protective pad 1 on the inner side of a metal guardrail, thereby preventing the driver from being injured due to the collision of the knee with the metal structure when accelerating or braking. In addition, a metal insert 2 is embedded in the protective pad to be connected to the protective pad as a whole, and then the protective pad is installed on the guardrail through the metal insert 2.

[0026] In a further solution, the end face diameter of the support plate is larger than the end face diameter of the locking cylinder 22. An axial hole 24 is provided at the center of the metal insert 2, and the protective pad 1 is fixed to the guardrail (the guardrail is not shown in the figure) by passing a bolt through the axial hole 24. The threaded end of the bolt passes through the axial hole 24 and connects with the threaded hole on the guardrail, so that the left support plate 21 abuts against the guardrail handle, and the nut end of the bolt is located on the outside of the right support plate 23. That is, the diameter of the nut must be larger than the aperture of the axial hole. This can avoid squeezing, deformation, etc. of the protective pad 1 when tightening the bolt.

[0027] The material of the protective pad 1 in the present application is plastic, and the preferred embodiment is a polyurethane foam pad. A mounting hole can be opened in advance on the periphery of the polyurethane foam substrate, and the locking cylinder 22 of the metal insert 2 can be embedded in the mounting hole, while the left and right support plates are located on the outside of the polyurethane foam substrate; and then the polyurethane foam substrate is subjected to a vacuum forming process to obtain the protective pad 1. As the vacuum forming process proceeds, the polyurethane foam material is heated and softened and filled between the mounting hole and the metal insert 2, thereby closely fitting with the inner side surfaces of the left and right support plates and the periphery of the locking cylinder 22, ensuring that the metal insert 2 and the protective pad 1 do not fall off.

[0028] The metal insert 2 is used as a support member for the polyurethane foam pad, which significantly reduces the use cost compared to fixing a large flat sheet metal member on the polyurethane foam pad as a support member.

[0029] The metal insert 2 serves as a connecting piece of the polyurethane foam pad. During installation, the protective pad 1 is fixed to the guardrail after a bolt is passed through the axial hole 24 of the metal insert 2, thereby avoiding squeezing and deformation around the polyurethane foam pad during fixation or prying of the edges due to the soft material of the polyurethane foam pad.

[0030] The inner side wall of the protective pad 1 is longitudinally spaced apart with a plurality of transverse convex strips 11, such as Figure 1 As shown, the transverse convex strips 11 are all over the inner wall of the protective pad 1, thereby increasing and thickening the contact surface, reducing the pressure when the knee contacts, and effectively relieving driving fatigue.

[0031] In order to adapt to the structure of the guardrail, the protective pad 1 is a square structure, and a U-shaped notch 12 is provided in the middle of the bottom end thereof; metal inserts 2 are respectively installed at the four corners of the protective pad 1 and on both sides of the U-shaped notch 12. Due to the U-shaped notch 12, the adaptability of the protective pad 1 to the guardrail is improved, and the shaft hole 24 on the metal insert 2 and the threaded hole on the guardrail are avoided to avoid inconvenience in installation.

[0032] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0033] 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.
