Background
In an elevator hoistway, the counterweight guard rail is required to be installed outside the elevator counterweight, so that the operation area of the counterweight is partitioned, and the situation that an operator is impacted by the operated counterweight to form injury after entering the hoistway is avoided. The current counterweight guardrail mainly comprises protection piece, stand and support, and wherein the protection piece is the sheet metal that the polylith set up side by side, and the both sides of protection piece are through stand linking bridge to fix in the elevator well through the support, realize the protection effect. However, when the counterweight guardrail is used for a heavy-duty elevator, the width of the counterweight device of the elevator is large, so that the length of the protective sheet can cause the reduction of the deformation resistance of the protective sheet after the protective sheet is elongated, and further the protective sheet is easy to bend at the collision part when the protective sheet is impacted by external force, thereby reducing the protection effect of the counterweight guardrail and affecting the lifting stability of the counterweight device.
Therefore, an elevator counterweight guardrail with strong deformation resistance and good protection effect is needed.
Disclosure of Invention
The utility model aims to provide a counterweight guardrail structure for a heavy-duty elevator. It has the characteristics of strong deformation resistance and good protection effect.
The technical scheme of the utility model is as follows: the counterweight guardrail structure for the large-load elevator comprises a middle upright post, wherein the two sides of the middle upright post are detachably connected with a protective sheet group, and one side of the protective sheet group far away from the middle upright post is connected with a plurality of guardrail supports through angle steel connecting columns; the protective sheet group is formed by arranging a plurality of protective sheets side by side up and down, the middle parts of the protective sheets form convex parts, and the protective sheets on two sides of the convex parts are provided with first connecting holes; and concave parts are formed on two sides of the middle upright post, and are provided with second connecting holes matched with the first connecting holes.
In the counterweight guardrail structure for the large-load elevator, the protection sheet and the middle upright post are formed by bending metal plates.
In the counterweight guardrail structure for the large-load elevator, the middle upright post is connected to one side, far away from the protruding part, of the protecting piece, the protecting pieces on two sides of the protruding part are mutually attached to the recessed part, and the outer end face of the protruding part and the outer end face of the middle upright post are mutually flush.
In the counterweight guardrail structure for the large-load elevator, the angle steel connecting column is connected to one side, far away from the protruding part, of the protection sheet.
In the counterweight guardrail structure for the heavy-duty elevator, two sides of the protruding part are connected with the protective sheet through symmetrical inclined planes, and the opening directions of the inclined planes at two sides are gradually opened from inside to outside.
In the counterweight guardrail structure for the large-load elevator, the concave part is connected with the middle upright post through the vertical surface, and the vertical surface and the middle upright post are mutually perpendicular.
Compared with the prior art, the utility model can split the original protective sheet in the extending direction by matching the middle upright post and the protective sheet groups at two sides, thereby shortening the length of a single protective sheet and improving the deformation resistance of the guardrail at the middle position by matching the middle upright post; the structural strength and the deformation resistance of the protection sheet and the middle upright post can be improved by bending the protection sheet and the middle upright post to form the convex part and the concave part, so that the possibility of stress deformation of the protection sheet and the middle upright post is reduced; on this basis, through the optimization of protective sheet and middle part stand connection structure and appearance, then can make the outer terminal surface of protective sheet and middle part stand parallel and level each other after connecting to when making the operation personnel collide it, this impact force can bear together by protective sheet and middle part stand, avoids the deformation that arbitrary position atress alone caused. Therefore, the utility model has the characteristics of strong deformation resistance and good protection effect.

Detailed Description
The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.
Examples. The counterweight guardrail structure for the heavy-duty elevator is shown in fig. 1, and comprises a middle upright post 1, wherein the two sides of the middle upright post 1 are connected with a protective sheet group through screws, one side of the protective sheet group far away from the middle upright post is connected with a plurality of guardrail supports 3 through angle steel connecting posts 2, two ends of the angle steel connecting posts 2 are respectively connected with the guardrail supports 3 and the protective sheet group through screws, and the guardrail supports 3 are made of metal plates; the protective sheet group is formed by arranging a plurality of protective sheets 4 side by side up and down, the middle part of the protective sheet 4 is provided with a convex part 5, and the protective sheets 4 on two sides of the convex part 5 are provided with first connecting holes; the two sides of the middle upright post 1 are provided with concave parts 7, and the concave parts 7 are provided with second connecting holes 8 matched with the first connecting holes.
