In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0027] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0028] As Figure 1 And Figure 2 shown, a device for preventing personnel from falling during loading and unloading of goods provided by an embodiment of the present utility model includes: a base 1, a column, and a wire releasing mechanism;
[0029] The lower end of the column is fixedly connected to the base 1;
[0030] The line-releasing mechanism includes a winding wheel 2, a fixed pulley 3, a carrying rope 4, a positioning rod 5 and a limiting ring 6. The fixed pulley 3 is rotatably connected to the upper end of the column, the positioning rod 5 is fixedly connected to the axial side of the column, the winding wheel 2 is horizontally rotatably arranged on the axial side of the column, one end of the carrying rope 4 is wound around the winding wheel 2, and the other end passes over the fixed pulley 3 and is connected to the hook 7, the wheel axle of the winding wheel 2 is fixedly connected to one end of the rocker 8, the other end of the rocker 8 is fixedly connected to the handle 9, the handle 9 is parallel to the positioning rod 5, and the limiting ring 6 is simultaneously sleeved on the handle 9 and the positioning rod 5, for fixing the distance between the handle 9 and the positioning rod 5.
[0031] The working process of the cargo loading and unloading protection device is as follows:
[0032] like Figure 4 and Figure 5 As shown, two cargo anti-falling devices are used in combination, and the bases 1 of the two anti-falling devices are respectively pressed under the front wheels of the truck 23 and the rear wheels of the truck 23 in diagonal directions (left front and right rear or right front and left rear), and the hook 7 of the front anti-falling device is hooked on the upper end of the column of the rear anti-falling device, and the hook 7 of the rear anti-falling device is hooked on the upper end of the column of the front anti-falling device;
[0033] The operator holds the handle 9, rotates the winding wheel 2, tightens the load-bearing rope 4, and simultaneously sleeves the limit ring 6 on the handle 9 and the positioning rod 5 to fix the distance between the handle 9 and the positioning rod 5, so that the handle 9 cannot swing at will, thereby making the winding wheel 2 unable to rotate, so that the load-bearing rope 4 maintains its tension, and the load-bearing rope 4 extends along the diagonal direction of the truck 23 body.
[0034] On this basis, the loading and unloading personnel on the truck 23 wear the safety belt and hook the hook 7 of the safety belt on the load-bearing rope 4. Even if the loading and unloading personnel step on empty space when walking back and forth on the truck 23, the load-bearing rope 4 can provide bearing capacity for the loading and unloading personnel through the safety belt, play a buffering role, and prevent people from falling and getting injured.
[0035] like Figure 2 As shown, specifically, one end of the positioning rod 5 is fixedly connected to the axial side of the column, and the extension direction of the positioning rod 5, the extension direction of the handle 9 and the extension direction of the axle of the winding wheel 2 are parallel to each other. When the winding wheel 2 rotates and the distance between the handle 9 and the positioning rod 5 is minimum, the limiting holes at both ends of the limiting ring 6 respectively sleeve the handle 9 and the positioning rod 5 (the limiting ring 6 is a long strip plate, and limiting holes are respectively provided at both ends of the limiting ring 6, and the distance between the two limiting holes is equal to the minimum distance between the handle 9 and the positioning rod 5), thereby fixing the distance between the handle 9 and the positioning rod 5, thereby preventing the uncontrolled rotation of the winding wheel 2 from causing the load-bearing rope 4 to loosen, thereby keeping the load-bearing rope 4 taut during use.
[0036] Specifically, the load-bearing rope 4 is made of a steel wire rope, and one end of the load-bearing rope 4 is fixedly welded or clamped to the inner edge of the wheel groove of the winding wheel 2 so that the load-bearing rope 4 can be wound in the wheel groove of the winding wheel 2.
[0037] Specifically, the front and rear wheels of the truck 23 are respectively pressed on the bases 1 of the two anti-falling devices, and the staff pulls the handbrake of the truck 23 so that the front and rear wheels of the truck 23 cannot rotate and are stably pressed on the base 1.
[0038] like Figure 1 As shown, in a specific embodiment, the column includes a sleeve 10 and a rotating rod 11, the lower end of the sleeve 10 is fixedly connected to the base 1, the lower end of the rotating rod 11 is inserted into the upper end of the sleeve 10, the winding wheel 2 is rotatably connected to the axial side of the rotating rod 11 through a bracket 12, and the fixed pulley 3 is rotatably connected to the upper end of the rotating rod 11.
[0039] In this embodiment, specifically, the lower end of the sleeve 10 is welded to the base 1, and the rotating rod 11 can rotate in the sleeve 10; because the lengths of trucks 23 of different models are not the same, the upper ends of the columns of the anti-fall device at the front and rear wheel positions are connected together by the load-bearing rope 4. After the load-bearing rope 4 is tightened, the rotating rod 11 can rotate appropriately in the sleeve 10, and the relative positions of the fixed pulleys 3 at the upper ends of the two rotating rods 11 can be passively adjusted appropriately, so that the wheel grooves of the two fixed pulleys 3 are facing each other, so that the load-bearing rope 4 is stabilized in the wheel groove of the fixed pulley 3, avoiding the load-bearing rope 4 from being separated from the wheel groove of the fixed pulley 3, so that the load-bearing rope 4 can provide stable bearing force for the bodies of loading and unloading personnel.
[0040] like Figure 1 As shown, in a specific embodiment, the column also includes a sleeve 13 and a support rod 14, the lower end of the sleeve 13 is fixedly connected to the upper end of the rotating rod 11, the lower end of the support rod 14 is inserted into the upper end of the sleeve 13, and the axial side of the support rod 14 is sequentially arranged with a plurality of first limiting holes 15, and the axial side of the sleeve 13 is provided with a second limiting hole 16, the second limiting hole 16 corresponds to one of the first limiting holes 15, and is used to make the limiting pin 17 pass through the first limiting hole 15 and the second limiting hole 16 in sequence, and the fixed pulley 3 is rotatably connected to the upper end of the support rod 14.
[0041] In this embodiment, specifically, the support rod 14 moves up and down relative to the sleeve 13 to adjust the height of the fixed pulley 3, and the limit pin 17 is inserted into the first limit hole 15 and the second limit hole 16, and the nut is connected to fix the height of the fixed pulley 3, thereby adjusting the height of the tensioned load rope 4 according to the height of the truck reference plane, and adjusting the height at which the safety belt can be hung.
[0042] like Figure 5As shown, in the specific embodiment, the cross-sections of the sleeve 13 and the support rod 14 are respectively rectangular, and the cross-sections of the sleeve 10 and the rotating rod 11 are respectively circular.
[0043] In this embodiment, the cross-sections of the sleeve 10 and the rotating rod 11 are respectively circular, and the rotating rod 11 can rotate relative to the sleeve 10 to adjust the relative positions of the two fixed pulleys 3 above the front and rear wheels; the cross-sections of the sleeve 13 and the support rod 14 are respectively rectangular, and the support rod 14 cannot rotate relative to the sleeve 13, so that the first limiting hole 15 and the second limiting hole 16 will not be horizontally misaligned, ensuring that the limiting pin 17 can be smoothly inserted into the first limiting hole 15 and the second limiting hole 16 in sequence.
[0044] As Figure 1 and Figure 5 shown, in the specific embodiment, it further includes a suspension ring 18, and the suspension ring 18 is fixedly connected to the upper side of the column.
[0045] In this embodiment, specifically, the hook 7 of one anti-falling device is hooked on the suspension ring 18 of another anti-falling device to prevent the hook 7 from detaching from the upper end of the column of another anti-falling device.
[0046] As Figure 1 and Figure 5 shown, in the specific embodiment, it further includes a moving mechanism, and the moving mechanism includes a hydraulic cylinder 19 and a roller 20. The hydraulic cylinder 19 is fixedly connected to the side of the base 1, and the lower end of the piston rod of the hydraulic cylinder 19 is rotatably connected to the roller 20 for driving the roller 20 to descend below the base 1.
[0047] In this embodiment, specifically, when the staff needs to move the position of the anti-falling device, control the piston rod of the hydraulic cylinder 19 to extend downward, drive the roller 20 to move downward below the base 1, then hold the column and pull the column and the base 1 to tilt at a certain angle synchronously, and the base 1 is separated from the ground, and only the roller 20 touches the ground, which is convenient for the staff to push the anti-falling device with less effort;
[0048] When the anti-falling device moves to a suitable position (that is, the relative positions of the bases 1 of the two anti-falling devices match the relative positions of the front and rear wheels of the truck 23), control the piston rod of the hydraulic cylinder 19 to contract upward, drive the roller 20 to move upward above the base 1, and the base 1 completely touches the ground. Then drive the truck 23 again, so that the front and rear wheels of the truck 23 press on the base 1 to fix the position of the base 1, and at the same time, the mechanical structures of the roller 20 and the hydraulic cylinder 19 will not be damaged.
[0049] As Figure 1 shown, in the specific embodiment, it further includes a cart handle 21, and the cart handle 21 is fixedly connected to the side of the base 1.
[0050] In this embodiment, specifically, the cart handle 21 and the hydraulic cylinder 19 are fixedly connected to the same side of the base 1. When moving the anti-falling device, the operator can hold the cart handle 21 and can relatively easily lift the base 1 so that the rollers 20 touch the ground alone.
[0051] As Figure 1 shown, in the specific embodiment, it further includes a guide rope hole member 22, and the guide rope hole member 22 is fixedly connected to the upper end side of the column for the load-bearing rope 4 to pass through the guide rope hole member 22.
[0052] In this embodiment, specifically, the load-bearing rope 4 passes through the guide rope hole member 22, which facilitates the load-bearing rope 4 to extend along the axial direction of the column, and finally enables the load-bearing rope 4 to stably pass through the gap between the fixed pulley 3 and the column and lap on the pulley groove of the fixed pulley 3.
[0053] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
