Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a safety operation cage for external side beams. Background Technology

[0002] When maintaining the outer side of bridge railings, an external hanging cage is required. (Refer to...) Figure 1 The top of the suspended cage is equipped with hooks, which are used to hang the entire cage on the bridge railing, and workers stand inside the cage to carry out the work. Because the hooks are fixed to the top of the cage, in order to ensure the stability of the cage, the cage needs to be close to the railing. This means that the size of the hooks must match the thickness of the bridge railing, and they cannot be adjusted, resulting in low applicability. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a safety operation cage for external side beams.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A safety hoisting cage for side beams includes a basket and two connecting arms. The connecting arms are arranged longitudinally, and the basket is positioned between the two connecting arms. A slider is fixed to the bottom of each connecting arm. A side plate is vertically mounted on the basket near each of the two connecting arms. A groove is formed on the side plate, and the sliders at the bottom of the two connecting arms are slidably connected to the grooves on the two side plates. The grooves are inclined. The top of each connecting arm is bent towards the side with the lower height of the groove to form a hook. A threaded sleeve is fixedly installed on each connecting arm, and a screw is threaded into the threaded sleeve. The screw is horizontally positioned and parallel to the side plate.

[0006] Furthermore, the slide is a through groove, and several studs are fixed to the opposite sides of the two sliders. A clamping plate is sleeved on the studs located on the same slider. Nuts are threaded onto the studs, and the side plate is clamped between the connecting arm and the clamping plate.

[0007] Furthermore, the hook includes a horizontal section and a vertical section. The vertical section is parallel to the connecting arm. The horizontal section is fixed between the vertical section and the connecting arm. A first roller is installed on the side of the vertical section near the connecting arm, and the axis of the first roller is longitudinally arranged. A second roller is installed at the bottom of the horizontal section, and the axis of the second roller is horizontally arranged. A third roller is installed on the side of each of the two side plates near the vertical section. The third roller protrudes from the bottom plate of the basket, and the axis of the third roller is longitudinally arranged.

[0008] Furthermore, a plurality of climbing railings are horizontally installed between the two side plates near the vertical section, and the plurality of climbing railings are arranged at intervals along the longitudinal direction.

[0009] Furthermore, a baffle is connected between the two side plates on the side away from the vertical section.

[0010] Furthermore, a connecting beam is fixed between the vertical sections of the two hooks.

[0011] The beneficial effects of this utility model are as follows: the hook can adapt to guardrails of different thicknesses, and has high applicability; the suspended basket and the connecting arm are movably connected, and when the hook is hung on the guardrail, the suspended basket can always fit against the outside of the guardrail under the action of gravity, which has high stability and ensures the safety of workers.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] like Figure 2 , Figure 3As shown, a safety operation cage for side beam external hanging includes a basket 1 and two connecting arms 2. The connecting arms 2 are arranged longitudinally, and the basket 1 is positioned between the two connecting arms 2. A slider 21 is fixedly connected to the bottom of the connecting arms 2. A side plate 11 is vertically arranged on the basket 1 near the two connecting arms 2. A baffle 12 is fixedly connected between the rear sides of the two side plates 11. A groove 111 is formed on the side plate 11. The sliders 21 at the bottom of the two connecting arms 2 are slidably connected to the grooves 111 on the two side plates 11. The grooves 111 are inclined at a 30° angle, with the front end of the groove 111 being the lower end. The top of the connecting arm 2 is bent forward to form a hook, which includes a water... The horizontal section 22 and the vertical section 23 are parallel to the connecting arm 2. The horizontal section 22 is fixed between the vertical section 23 and the connecting arm 2 and extends in the front-back direction. A first roller 3 is installed on the side of the vertical section 23 near the connecting arm 2. The axis of the first roller 3 is set longitudinally. A second roller 4 is installed at the bottom of the horizontal section 22. The axis of the second roller 4 extends in the front-back direction. A third roller 5 is installed on the front side of each of the two side plates 11. The third roller 5 protrudes from the bottom plate of the basket 1 and the axis of the third roller 5 is set longitudinally. A threaded sleeve 6 is fixedly installed on the connecting arm 2. A screw 7 is internally threaded to the threaded sleeve 6 and extends in the front-back direction.

[0019] like Figure 4 As shown, in actual use, the hook is hung on the guardrail 10, with the vertical section 23 of the hook located inside the guardrail 10, the first roller 3 in contact with the inner side of the guardrail 10, the horizontal section 22 of the hook located at the top of the guardrail 10, the second roller 4 in contact with the top surface of the guardrail 10, and the screw 7 is turned so that the screw 7 is close to the outer side of the guardrail 10. Under the action of gravity, the cage slides diagonally downward along the slide groove 111 until the third roller 5 abuts against the outside of the guardrail 10. Workers can stand on the basket 1 to work, and can also use their hands to support the outside of the guardrail 10, so that the entire device rolls along the extension direction of the guardrail 10.

[0020] In this embodiment, the slide groove 111 is a through groove, and two studs 211 are fixedly connected to the opposite sides of the two sliders 21. A clamping plate 8 is sleeved on the two studs 211 located on the same slider 21. Nuts are threaded on the studs 211 to prevent the clamping plate 8 from falling off the studs 211. The side plate 11 is clamped between the connecting arm 2 and the clamping plate 8. The design is reasonable and can effectively prevent the basket 1 from detaching from the connecting arm 2.

[0021] In this embodiment, several climbing railings 13 are horizontally installed between the front sides of the two side plates 11. The climbing railings 13 are arranged at intervals along the longitudinal direction to facilitate workers to go up / down the guardrail 10.

[0022] In this embodiment, a connecting beam 9 is provided between the vertical sections 23 of the two hooks. The two ends of the connecting beam 9 are respectively connected to the vertical sections 23 of the two hooks by bolts. The connection beam 9 improves the overall integrity of the two hooks.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
