Description
Technical Field
The utility model relates to the field of hoisting equipment, in particular to a safety protection device for a trolley edge of a hoisting machine.
Background
The large metallurgical casting crane is an overhead bridge crane, the volume of a trolley is large, and the distance from the large bridge crane is generally more than 2 meters. During production, the crane cart runs transversely and the trolley runs longitudinally. Safety guardrails are arranged at two longitudinal ends of the trolley, and the left side and the right side lack edge protection devices. In the daily use management process of the hoisting machinery, an operator can go up and down the crane trolley to perform spot inspection and maintenance before and during the work, and the risk of falling injury of the side of the operator in the high place exists.
Disclosure of Invention
The utility model aims to solve the problem that the falling risk exists in the overhauling operation of an operator on and off a trolley of a crane in the actual production of the existing crane, and provides a safety protection device for the adjacent side of the trolley of the crane.
The specific scheme of the utility model is as follows: be used for jack-up machinery platform truck to face limit safety device, including the bottom plate, bottom plate top edge is equipped with a plurality of vertical pole setting along the limit, is equipped with the horizontal pole between every two adjacent pole setting, and the guardrail is enclosed to pole setting and horizontal pole, and the guardrail is equipped with the exit, and the exit sets up between two adjacent pole setting, two adjacent pole setting tops all are equipped with the jack, are equipped with the protection chain between two jacks, the protection chain includes the bolt of cartridge in corresponding jack, is equipped with a chain between two bolts.
The guardrail is provided with a plurality of inlets and outlets, and each inlet and outlet is provided with the protection chain.
The cross rod is provided with an upper layer and a lower layer, a lower layer cross rod is arranged between all the upright rods, and an upper layer cross rod is arranged at the top of each upright rod at a position avoiding an inlet and an outlet.
The upright rod is made of steel pipes.
The bolt is made of a round rod, one end of the round rod, which is close to the chain, is provided with a check ring, and the diameter of the check ring is larger than that of the jack.
Compared with the prior art, the utility model has the following advantages: the installation cost is low, the operation is convenient, the falling of operators during the operation of the crane trolley can be effectively prevented, and the falling injury accident of the operators is avoided.

Detailed Description
Referring to fig. 1-4, the embodiment is a safety protection device for a trolley of hoisting machinery, comprising a bottom plate 1, wherein the bottom plate 1 is made of steel plates with the thickness of 10-12mm, the bottom plate 1 is welded on a trolley body, a plurality of vertical rods 2 are arranged along the edge of the top edge of the bottom plate 1, the vertical rods 2 are vertically welded on the bottom plate 1 by steel pipes with the diameter of 50mm and the wall thickness of 5mm, a cross rod 3 is arranged between every two adjacent vertical rods 2, the vertical rods 2 and the cross rod 3 form a guardrail, the guardrail is provided with an inlet and an outlet, the inlet and the outlet are arranged between the two adjacent vertical rods 2, jacks are arranged at the tops of the two adjacent vertical rods 2, a protection chain is arranged between the two jacks, the protection chain comprises a plug pin 5 which is inserted in the corresponding jacks, a round rod with the diameter of 30mm and the length of 200-250mm is arranged between the two plug pins 5, one end of the round rod close to the chain 4 is provided with a check ring, and the diameter of the check ring is larger than the diameter of the jacks.
Furthermore, the guardrail is provided with a plurality of inlets and outlets, and each inlet and outlet is provided with the protection chain.
Furthermore, the cross rod 3 is provided with an upper layer and a lower layer, the lower layer cross rod 3 is arranged between all the vertical rods 2, and the upper layer cross rod 3 is arranged at the top of the vertical rods 2 at the position avoiding the inlet and the outlet.
When the protective fence is used, an operator pulls out one of the bolts 5 of the protective chain before entering the trolley body from the inlet and the outlet, then enters the protective chain, and inserts the pulled-out bolt 5 back to the original position after entering and standing to form the closed protective fence, so that the risk of unexpected falling of the operator is avoided, the bolt 5 can naturally sag after being pulled out, and the bolt 5 at the other end of the chain 4 can still be kept at the top of the upright rod 2 due to the length limitation.
