Description

Technical Field

[0001] This utility model belongs to the technical field of manual stacker protection equipment, and specifically relates to a safety protection frame for manual stackers. Background Technology

[0002] Bearing manufacturers typically have large warehouses with high ceilings. After the bearings are packaged, they are placed on shelves. When picking up and placing goods for shipment, the distance between the shelves is limited, so manual stackers are usually used.

[0003] Currently, commercially available manual stackers only have a safety net installed on the side of the fork carriage closest to the operator, while there is no protective mechanism around the forks. When the rack is high, the forks need to be raised to a higher position to pick up and put down goods. During the picking, putting down and transfer process, the goods are prone to shaking and falling due to uneven ground or turning, which poses a safety risk.

[0004] Based on this, we developed a safety guard for manual stackers. Utility Model Content

[0005] The purpose of this utility model is to provide a safety protection frame for a manual stacker truck, aiming to solve the problems existing in the prior art mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A safety guard for a manual stacker includes a manual stacker with a fork carriage and forks, and also includes a guard. The guard includes a support railing fixed to the top of the fork carriage, and side railings detachably connected to the left and right sides of the support railing. The forks are located between the two side railings. The space formed by the guard, fork carriage, and forks can effectively limit the movement of goods.

[0008] Furthermore, the supporting guardrail includes parallel, spaced-apart support rods. A first horizontal bar, a second horizontal bar, and a third horizontal bar are sequentially spaced from top to bottom between the support rods. The supporting guardrail is provided with positioning grooves, which are strip-shaped through holes open at one end. The positioning grooves are respectively located at both ends of the first and third horizontal bars, and their openings are formed on the adjacent support rods. The side guardrails are provided with corresponding, spaced-apart positioning rods that pass through the positioning grooves. The supporting guardrail and the side guardrails are connected by bolts, allowing adjustment of the distance between the two side guardrails to accommodate goods of different sizes.

[0009] Furthermore, the first crossbar and the third crossbar are respectively provided with a first positioning hole that runs vertically through the top and bottom, and the first positioning hole has a positioning groove that runs vertically through the bottom and bottom. The positioning rod is provided with a second positioning hole that runs vertically through the top and bottom. Multiple second positioning holes are evenly distributed along the axial direction of the positioning rod. The first positioning hole and the second positioning hole that are aligned and connected are connected by bolts.

[0010] Furthermore, the bottom of the support rod is provided with a connecting seat, which is fixed to the fork frame by bolts.

[0011] Furthermore, the side guardrail includes a rectangular support frame, and the rectangular support frame is provided with multiple limiting rods, which are distributed in a grid pattern.

[0012] Furthermore, the upper horizontal bar of the support frame is aligned with the height of the first horizontal bar, the lower horizontal bar of the support frame is aligned with the height of the fork, one side vertical bar of the support frame is aligned with the fork carriage, and the other side vertical bar is aligned with the end of the fork.

[0013] Compared with the shortcomings and deficiencies of the prior art, the present invention has the following beneficial effects.

[0014] 1. This utility model provides a safety guard for a manual stacker truck. The support guardrail works with the fork frame to protect the goods from the rear, and the side guardrails protect the goods from the sides. The forks support the goods from the bottom, thus forming a relatively complete protective space. This can effectively solve the problem of goods falling due to shaking during the lifting and transfer of goods in existing manual stackers. Especially in bearing manufacturing enterprises, the weight of the goods is generally large, which can effectively reduce the risk of goods falling and injuring people.

[0015] 2. The side guardrails on both sides are slidably connected to the positioning grooves on the supporting guardrails via positioning rods, and their positions are fixed by bolts. This allows for easy adjustment of the spacing between the side guardrails to accommodate goods of similar width, improving the versatility of the protective frame. This protective railing is inexpensive to manufacture, requires no major modifications to manual stackers, and is highly practical. Attached Figure Description

The manual stacker 100 has a fork carriage 110 and a lifting mechanism. The lifting mechanism is used to drive the fork carriage 110 to move up and down. Forks 120 are arranged at intervals on the fork carriage 110, and the forks 120 are used to pick up and place goods on pallets.

[0024] This utility model discloses a safety guard for a manual stacker, including a manual stacker 100 and a guard 200. The guard 200 is installed on the fork frame 110 and is used to prevent goods from tipping over and falling when the manual stacker 100 picks up goods.

[0025] Reference Figure 2 The protective frame 200 includes a support railing 210 and two sets of side railings 220 (see reference). Figure 4 The support railing 210 includes two parallel support rods 217 spaced apart. A first horizontal bar 212, a second horizontal bar 213, and a third horizontal bar 214 are sequentially spaced between the support rods 217 from top to bottom. A connecting seat 211 is provided at the bottom of each support rod 217, and a fixing groove is provided at the bottom of the connecting seat 211. The top of the fork 110 is embedded in the fixing groove, and the fork 110 is fixed to the connecting seat 211 by bolts. In this embodiment, the first horizontal bar 212, the second horizontal bar 213, the third horizontal bar 214, and the support rods 217 are fixed by welding.

[0026] Reference Figure 2 Two sets of side guardrails 220 are respectively vertically installed on the left and right sides of the supporting guardrail 210. The side guardrails 220 and the supporting guardrail 210 are detachably connected, preferably by bolts. (Refer to...) Figure 3The side guardrail 220 includes a rectangular support frame 224. The upper horizontal bar of the support frame 224 is aligned with the first horizontal bar 212 of the support guardrail 210, and the lower horizontal bar of the support frame 224 is aligned with the fork 120. One side vertical bar of the support frame 224 is close to the fork carriage 110, and the other side vertical bar is close to the end of the fork 120. A grid structure limiting bar 223 is fixedly connected inside the support frame 224.

[0027] Reference Figure 4 The support railing 210 is provided with a positioning groove 215, which is a long strip through hole. The positioning groove 215 is respectively opened at both ends of the first horizontal bar 212 and the third horizontal bar 214, and the end of the positioning groove 215 is horizontally connected to the support rod 217 on the adjacent side. The positioning groove 215 forms a one-sided opening. The first horizontal bar 212 and the third horizontal bar 214 are both provided with a first positioning hole 216 that is vertically connected. The first positioning hole 216 is vertically connected to the positioning groove 215, and the first positioning hole 216 is respectively opened at the end near the first horizontal bar 212 and the third horizontal bar 214.

[0028] Reference Figure 3 The support frame 224 has a vertically connected positioning rod 221 on the side of the fork 110. Two positioning rods 221 are arranged parallel to each other on the vertical rod. The two positioning rods 221 correspond to the positions of the first crossbar 212 and the third crossbar 214, respectively. The two positioning rods 221 are used to pass through the positioning grooves 215 of the first crossbar 212 and the third crossbar 214, respectively. The positioning rod 221 has a second positioning hole 222 that runs vertically through it. Multiple second positioning holes 222 are evenly opened along the axial direction of the positioning rod 221. The first positioning hole 216 and the second positioning hole 222 are fixed by bolts, thereby fixing the relative position of the side guardrail 220 and the support guardrail 210, and facilitating the adjustment of the distance between the two side guardrails 220.
