Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a bridge construction operating platform with safety protection. Background Art

[0002] In order to facilitate the operation on the bottom of the bridge during bridge construction, it is necessary to use an operating platform suspended at the bottom of the bridge. The operating platform currently used is a hanging basket, which is hung at the bottom of the bridge by a crane, and then the staff stand on the operating platform to perform construction operations.

[0003] The existing hanging basket is suspended at the bottom of the bridge by a crane. When the workers stand on it to perform construction operations, the hanging basket will shake when the workers move and change positions on the hanging basket, which affects safety. In order to prevent the hanging basket from shaking, the crane will lift the hanging basket so that the top of the hanging basket fits the bottom of the bridge, thereby improving safety. However, after the hanging basket is against the bottom of the bridge, the longitudinal space from the hanging basket to the bottom of the bridge is insufficient. When the workers walk and perform construction operations, they need to bend or even squat, which makes it inconvenient for the workers to move and operate. Therefore, we propose a bridge construction operation platform with safety protection. Utility Model Content

[0028] A base 1, with guardrails 11 fixed to both side walls of the base 1, and the base 1 and the guardrails 11 form a hanging basket;

[0029] The number of the horizontal plates 2 is two, and the two horizontal plates 2 are respectively installed on the two side walls of the guardrail 11. Both ends of the horizontal plates 2 are connected with adjustment plates 3, and the adjustment plates 3 are fixed to the corresponding positions of the side walls of the guardrail 11;

[0030] Electric push rods 23, the number of which is four, the tail ends of the four electric push rods 23 are fixedly connected with carrier blocks 22, the four carrier blocks 22 are respectively installed on both sides of the top of the two horizontal plates 2, and the top of the electric push rods 23 is fixedly connected with a support plate 24;

[0031] In actual use, first, the hanging basket composed of the base 1 and the guardrail 11 is suspended on the lower side of the bottom of the bridge by a crane, and then the support plate 24 is lifted by the electric push rod 23, so that the support plate 24 is pressed against the bottom of the bridge, so that the guardrail 11 and the base 1 as a whole can be firmly fixed on the lower side of the bridge, and ensure that there is enough space between the bottom of the base 1 and the bottom of the bridge, which is convenient for the staff to carry out construction operations. At the same time, when the staff walks on the top of the base 1, the overall device is stable to avoid shaking, thereby improving the safety protection performance.

[0032] Furthermore, rubber blocks are embedded at the four corners of the bottom of the base 1. The provision of the rubber blocks allows the device to be supported when placed on the ground when not in use, thereby preventing the bottom of the base 1 from directly contacting the ground and being easily worn.

[0033] Furthermore, a limit slide groove is provided on the top of the transverse plate 2 , and matching limit sliders 21 are inserted into both sides of the inner cavity of the limit slide groove, and the top of the limit slider 21 is fixedly connected to the bottom of the corresponding carrier block 22 .

[0034] When the electric push rod 23 is used to drive the support plate 24 to lift and support the bottom of the bridge, the carrier block 22 is directly pulled so that it can move when the limit slider 21 is limited, thereby adjusting the support position, so that it can adapt to different positions of the bottom of the bridge for tight support, thereby improving the adaptability of the device.

[0035] like Figure 1 and 3 As shown; the top of the support plate 24 is provided with a plurality of evenly distributed slots, the inner cavity of the slot is plugged with an adaptable movable block 25, the bottom of the movable block 25 is fixedly connected with a spring 26, and the tail end of the spring 26 is fixed to the bottom of the inner cavity of the slot;

[0037] Furthermore, the top of the movable block 25 is provided with anti-skid grooves, and the provision of the anti-skid grooves can increase the friction when the movable block 25 is pressed against the bottom of the bridge, thereby facilitating the improvement of the stability of the pressing.

[0038] like Figure 1 and 2 As shown; a vertically arranged strip groove is opened on one side wall of the adjustment plate 3, a screw motor 31 is fixed at the bottom of the inner cavity of the strip groove, a screw 32 is fixedly connected to the outer end of the transmission shaft of the screw motor 31, the outer end of the screw 32 is rotatably connected to the top of the inner cavity of the strip groove, an outer wall of the screw 32 is sleeved with an adapted screw slider 33, and the outer wall of the screw slider 33 is fixedly connected to the corresponding end of the horizontal plate 2;

[0039] The screw motor 31 drives the screw 32 to rotate, driving the screw slider 33 to descend, thereby driving the cross plate 2 to descend, so that the electric push rod 23 and the support plate 24 can be lowered, so as to avoid space obstacles when moving the hanging basket and prevent the electric push rod 23 from being damaged by impact.

[0040] The implementation principle of the bridge construction operation platform with safety protection in the present application is as follows: in actual use, first, the hanging basket composed of the base 1 and the guardrail 11 is suspended on the lower side of the bottom of the bridge by a crane, and then the support plate 24 is lifted by the electric push rod 23, so that the support plate 24 is pressed against the bottom of the bridge, so that the guardrail 11 and the base 1 as a whole can be firmly fixed on the lower side of the bridge, and ensure that there is enough space between the bottom of the base 1 and the bottom of the bridge, which is convenient for the workers to carry out construction operations. At the same time, when the workers walk on the top of the base 1, the device as a whole is stable to avoid shaking. When the electric push rod 23 is used to drive the support plate 24 to lift and support it on the bottom of the bridge, the load block 2 is directly pulled. 2 enables it to move when the limit slider 21 is limited, so as to adjust the support position, so as to adapt to different positions of the bottom of the bridge for tight support, and when the support plate 24 is tightly fitted to the bottom of the bridge, it can drive the movable block 25 to compress the spring 26, so as to adapt to different shapes of different positions of the bottom of the bridge, so as to ensure the fit when tight support, when not in use, the screw motor 31 drives the screw 32 to rotate, drives the screw slider 33 to descend, so as to drive the cross plate 2 to descend, so as to make the electric push rod 23 and the support plate 24 descend, so as to avoid space obstacles when moving the hanging basket, and avoid the electric push rod 23 from being damaged by impact.
