Description

Technical Field

[0001] The utility model belongs to the technical field of logistics transportation equipment, and particularly relates to a falling prevention device for loading personnel of a freight truck. Background Art

[0002] During the loading process of a freight truck, since the side plates on both sides of the freight truck do not provide fall prevention protection for the loading personnel, it often happens that the personnel fall from the freight truck during the loading process. For example, a freight truck with an adjustable loading space, with the patent number CN202023164543.7, includes a carriage. A partition board is arranged in the carriage, and a lifting device for driving the partition board to move up and down is arranged in the carriage. Lifting columns are arranged at the four corners of the carriage, the upper ends of the lifting columns are connected to the top plate of the carriage, and a hoisting device is arranged on the top plate of the carriage; by adjusting the height of different loading spaces of the cargo box, the space of the carriage can be utilized more reasonably, thereby improving the transportation efficiency and reducing the transportation cost. However, the freight truck in the above patent does not have a fall prevention protection function and cannot protect the loading personnel of the freight truck from falling. Therefore, we urgently need a device that can protect the vehicle loading personnel. Summary of the Utility Model

[0003] The utility model provides a falling prevention device for loading personnel of a freight truck, which is convenient for installation and disassembly and can prevent the loading personnel in the carriage from falling, so as to solve the deficiencies of the prior art.

[0004] To achieve the above object, the utility model first proposes a falling prevention device for loading personnel of a freight truck, which includes a base, a protection frame hinged to the top of the base, an interception net arranged inside the protection frame, an elastic support member installed between the protection frame and the base, and a plurality of installation mechanisms fixedly installed at the bottom of the base and detachably connected to the side plate of the freight truck. The installation mechanism includes an inverted U-shaped installation clamping plate fixedly installed at the bottom of the base. The opening of the installation clamping plate faces downward. The installation clamping plate includes two vertical plates and a top plate fixed to the tops of the two vertical plates. The two vertical plates and the top plate enclose a clamping area matching the thickness of the side plate of the freight truck. An adjusting rod is threadedly connected to the vertical plate. One end of the adjusting rod extends into the clamping area, and a pressing disc is rotatably installed thereon. The other end of the adjusting rod extends out from the side of the vertical plate away from the clamping area, and a handwheel body convenient for rotating the adjusting rod is fixed thereto.

[0005] In this embodiment, a rubber layer disc with anti-slip particles is fixed on one side of the pressing disc in contact with the side plate of the truck. A buffer layer is fixed on the side wall of the vertical plate in the clamping area. Before loading the truck, the device is clamped on the top of the side plate of the truck through the mounting splints, and then the handwheel body is rotated to drive the pressing disc to move, so that the mounting splints are clamped with the side plate of the truck. By using the rubber layer disc installed on one side of the pressing disc and cooperating with the buffer layer, the friction force is enhanced, and the fixing effect of the mounting splints on the side plate of the truck is further improved, firmly fixing the protective frame on the side plate of the truck. Multiple such devices can be placed on the side plate of the truck, so as to use the protective frame with an interception net arranged on the top of the base to protect the loading personnel and prevent the loading personnel from falling.

[0006] In this embodiment, a rotating rod is rotatably installed between the two vertical plates of the mounting splint at the top of the clamping area. A support cylinder is fixedly installed on the outer surface of the rotating rod. By using the support cylinder, after the mounting splint is clamped on the side plate of the truck, the support cylinder contacts the top of the side plate of the truck. In this way, before it is fixed tightly, the mounting splint can slide along the side plate of the truck, so as to facilitate the adjustment of the position of the interception net.

[0007] In this embodiment, two grooves are opened at the bottom of each of the two mounting splints, and sliding rollers are rotatably installed inside the grooves. This facilitates the movement of the device on the ground.

[0008] In this embodiment, the elastic support member includes a hinge seat, a damper, a mounting plate and a support spring. Hinge seats are installed on the top surface of the base and on the side of the protective frame facing the base. One side of the two adjacent hinge seats is hinged with a mounting plate. A damper is installed between the two mounting plates, and a support spring is sleeved outside the damper. The two ends of the support spring are respectively fixedly connected to the two mounting plates. After the protective frame is impacted, on the one hand, through the compression of the support spring and the contraction of the damper, the impact force is alleviated to prevent the staff from being injured. On the other hand, under the combined action of the support spring and the damper, the rotation amplitude of the protective frame is prevented from being too large, and the protective frame will not bounce immediately after rotation, playing a good anti-fall protection effect on the staff.

[0009] In this embodiment, a buffer sponge cylinder is arranged on the top of the protective frame. The buffer sponge cylinder serves the purpose of protecting the staff and avoiding the staff being directly injured by hitting the cross bar of the protective frame.

[0010] Due to the adoption of the above structure, before loading the goods on the rear shelf of the truck, the two mounting splints at the bottom of the base of the device are placed on the side plate of the truck. The protective frame hinged on the top of the base and the interception net inside the protective frame are used to protect the loading personnel. By rotating the handwheel body to drive the adjusting rod to rotate and drive the pressing disc to move, the mounting splints are clamped on the side plate of the truck, and the base and the protective frame are firmly installed on the shelf, thus preventing the loading personnel from falling.

[0019] The installation mechanism 5 includes an inverted U-shaped installation clamping plate 51 fixedly installed at the bottom of the base 1. The opening of the installation clamping plate 51 faces downward. The installation clamping plate 51 includes two vertical plates and a top plate fixed to the tops of the two vertical plates. The two vertical plates and the top plate enclose a clamping area that matches the thickness of the truck side panel. A regulating rod 52 is threadedly connected to the vertical plate. One end of the regulating rod 52 extends into the clamping area, and a pressing disc 53 is rotatably installed thereon. The other end of the regulating rod 52 extends from the side of the vertical plate away from the clamping area, and a handwheel body 54 is fixed thereto. In order to reduce waste of resources, the handwheel body 54 is provided as a hollow type.

[0020] A rubber layer disc 6 with anti-slip particles is fixed to the side of the pressing disc 53 in contact with the truck side panel. A buffer layer 7 is fixed to the side wall of the vertical plate within the clamping area.

[0021] In this embodiment, before loading the truck, the device is clamped to the top of the truck side panel through the installation clamping plate 51, and then the handwheel body 54 is rotated to drive the pressing disc 53 to move, so that the installation clamping plate 51 is clamped to the truck side panel. And by using the rubber layer disc 6 installed on one side of the pressing disc 53 and cooperating with the buffer layer 7, the friction force is enhanced, and the fixing effect of the installation clamping plate 51 on the truck side panel is further improved, so that the protection frame 2 is firmly fixed on the truck side panel. Multiple such devices can be placed on the truck side panel, so as to use the protection frame 2 containing the interception net 3 provided on the top of the base 1 to protect the loading personnel and prevent the loading personnel from falling.

[0022] Such as Figure 3 、 4 As shown, a rotating rod 8 is rotatably installed between the two vertical plates of the installation clamping plate 51 at the top of the clamping area. A support cylinder 9 is fixedly installed on the outer surface of the rotating rod 8. By using the support cylinder 9, after the installation clamping plate 51 is clamped to the truck side panel, the support cylinder 9 contacts the top of the truck side panel. In this way, before it is fixed tightly, the installation clamping plate 51 can slide along the truck side panel, so as to facilitate the adjustment of the position of the interception net 3. Further, two grooves 11 are opened at the bottom of each of the two installation clamping plates 51, and a sliding roller 12 is rotatably installed inside the grooves 11, which facilitates the movement of the device on the ground.

[0023] Such as Figure 2As shown in the figure, the elastic support member 4 includes a hinge seat 41, a damper 42, a mounting plate 43, and a support spring 44. Hinge seats 41 are installed on the top surface of the base 1 and on the side of the protective frame 2 facing the base 1. One side of the two adjacent hinge seats 41 is hinged with a mounting plate 43. A damper 42 is installed between the two mounting plates 43. A support spring 44 is sleeved outside the damper 42. The two ends of the support spring 44 are fixedly connected to the two mounting plates 43 respectively. After the protective frame 2 is impacted, on the one hand, through the compression of the support spring 44 and the contraction of the damper 42, the impact force is alleviated to prevent the staff from being injured. On the other hand, under the combined action of the support spring 44 and the damper 42, it is prevented that the rotation amplitude of the protective frame 2 is too large, and the protective frame 2 will not bounce immediately after rotation, which has a good anti-falling protection effect on the staff.

[0024] As Figure 1 shown in the figure, a buffer sponge cylinder 10 is provided at the top of the protective frame 2. The buffer sponge cylinder 10 serves the purpose of protecting the staff and preventing the staff from being directly injured by hitting the cross bar of the protective frame 2.

[0025] During specific use, before the truck is loaded with goods, the two mounting clamping plates 51 at the bottom of the base 1 of this device are placed on the side plate of the truck. By placing multiple such devices on the side plate of the truck, the side plate of the truck is filled up. By rotating the hand wheel body 54, the adjusting rod 52 is driven to rotate, thereby driving the pressing disc 53 to move. The side plate of the truck is clamped by the pressing disc 53 and the inner wall of the mounting clamping plate 51, so that this device is firmly installed on the side plate of the truck.

[0026] The above is only the preferred embodiment of the present utility model, and thus does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
